Nightmare
① Nightmares are very common among children, mostly at the age of 3-7. "Nightmare" refers to the content that can be vividly recalled after waking up from a nightmare. These dreams are always terrible, which makes the dreaming children in extreme anxiety, or played by monsters, or chased by bad guys and beasts, or they and their relatives are on the verge of some kind of disaster, and so on. At that time, they couldn't even think about it, and they couldn't escape. They were often helpless and out of breath. When I am about to wake up, I often feel that my body and limbs are hard to move, as if I were pinned down by something. It takes several struggles to fully awake.
Nightmares occur in rem sleep with dreams. Because rapid eye movement sleep accounts for a high proportion in the second half of the night, the frequency of nightmares is higher in the second half of the night. At that time, the heartbeat and breathing may be accelerated, but there will be no obvious spontaneous response. When children wake up from nightmares, they often cry and say they are afraid. Parents' comfort can calm them down and go back to sleep.
Psychologists have analyzed that most children had psychological contradictions and emotional anxiety before having nightmares, or they felt uncomfortable during sleep because they watched horrible TV and listened to horrible stories, such as their noses covered with blankets and their chests oppressed by quilts. Some children may have poor breathing due to a cold, or sleep discomfort due to intestinal parasitic diseases, or feel hungry or full, which may induce nightmares.
② Nightmare refers to the sleep disorder in which children mainly have nightmares. Common in preschool and school-age children. They dreamed of falling from tall buildings, facing the abyss and being hunted down. At this time, it may be accompanied by rapid heartbeat, shortness of breath, feeling that the whole body can't move, trying to call for help but unable to make a sound, or being scared or awakened. Physical activity and groaning before waking up; After waking up, I have obvious emotional anxiety, pale face, cold sweat, and can recall my dreams. If the fear is lifted immediately, the child can sleep again.
There are five reasons: first, I was unhappy before going to bed that night. The second is to watch horror movies or listen to horror stories such as ghosts and gods and detectives. Third, sleeping posture is not good, such as putting your hands on your chest. Fourth, respiratory diseases or intestinal parasitic diseases caused by poor breathing. Fifth, overeating and bloating.
The correct way is to eliminate the above related factors, correct bad sleep habits and pay attention to the law of life at ordinary times. Don't use intimidation to educate children, restrict children from watching exciting movies and TV, and don't tell children ghosts and horror novels to avoid their emotional tension. Treat his physical illness in time. Frequent nightmares can be controlled by using a small dose of diazepam in a short time.
(3) A nightmare is a nightmare. As far as the word "Yan" is concerned, Xu Shen said in Shuo Wen Jie Zi: "Yan is also a dream." The word garden is interpreted as "an ominous sign in sleep" and Guang Yun simply interpreted it as "a nightmare". I often scream and moan because I seem to see or encounter terrible things in my dreams. This kind of dream is very exciting for people, and the dreamer can clearly recall the content of the dream after waking up. These dreams make people feel very frightened, and make people in extreme anxiety, or play with monsters, playing in the palm of their hands; Or chased by vicious people and hungry animals; Or your relatives and friends are on the verge of some kind of disaster ... when you want to shout, your throat seems to be blocked by something and you can't shout it out; When I tried to escape, my legs seemed to be tied behind someone's hands. I couldn't escape, so I was helpless, breathless and almost suffocated. When I am about to wake up, I often feel that my body and limbs are hard to move, as if I were tied up by something. After many twists and turns, I finally woke up. By this time, I was already in a cold sweat, and my three souls had been scared away. Some dreamers think that this is caused by the oppression of the dreamer's soul.
Nightmares have both external physical stimulation and internal psychological trauma. External factors, nightmares are mostly covered with a quilt to sleep, or hand pressure on the chest. When people sleep, the activity ability of heart and lungs is relatively weakened, so when the mouth and nostrils are blocked by quilts or the chest is compressed, they will feel that their heart activity is blocked and they have difficulty breathing. This kind of stimulation from the outside quickly spread to the cerebral cortex, causing incorrect reactions, so nightmares were born. Some people see ghosts pouncing on themselves in their dreams, trying to eat themselves, so they want to struggle and shout, but the part of the brain that commands muscle movements and sounds of hands and feet is still in a state of inhibition, so they want to struggle in their dreams, but their hands and feet can't move; I want to shout, but I can't make a sound. In addition, some people suffer from some chronic diseases, such as chronic tonsillitis, chronic rhinitis and chronic bronchitis. These diseases often have the problem of poor breathing, so it is easy to have nightmares during sleep.
Judging from the internal causes of nightmares, the dreamer must have been mentally stimulated before having nightmares, leaving an incurable psychological trauma. When people are awake, they rely on reason to dominate their lives. Therefore, the psychological trauma left by them in their early years is suppressed by reason, and it is difficult to "talk" freely. When people fall asleep, reason loses its authoritative role and consciousness weakens. The subconscious appeared, and the psychological trauma left by the dreamer in his early years was "expressed" with the help of nightmares. Han Yu said in the poem "Youxi Temple": "Wandering in the waves has become a nightmare." It can be seen that nightmares are indeed associated with fear and vigilance.
Modern psychologists believe that the reason why people have nightmares is usually related to some things that dreamers are afraid of in childhood, which can be traced back to the childhood when people can't help themselves. Children aged three to six are most likely to have nightmares. Once an adult feels that his safety is not guaranteed, or remembers some frightening and disturbing things in the past, he may also have nightmares.
(4) What is a nightmare? A nightmare is a ghost.
Nightmares are hard, but when you are awake, you can't make a sound, and you can't move your limbs, just like a soul is attached to a corpse. Not only that, at this time, the brain will be eager to fall asleep, people will fall asleep irresistibly, their eyes will gradually turn black and their consciousness will be blurred. But at this time, out of the desire for consciousness and the instinct of fear of nightmares, people try to get rid of nightmares and wake up immediately, but they can't get up because they can't move. At this time, if someone touches you or calls your name, you can wake up immediately.
As we all know, nightmares have a high probability of appearing in ghost novels and are often regarded as ghosts in rumors. This is because the probability of hallucinations during nightmares is also high.
Tell a story first. An authoritative research institution in the United States investigated people who claimed to have seen aliens and communicated with them, and used a lie detector when telling that experience, eliminating 70% rumors. In the survey of hundreds of other people, the researchers found that their experiences had amazing acquaintances-almost all claimed to wake up in the middle of the night and find aliens visiting their homes. Some said that they disappeared after seeing aliens strolling in the bedroom, while others claimed that they were invited to talk in a alien ufo.
There are two questions here: whether their experience is true or not, and why the polygraph can't detect that they are lying. Since they didn't lie, why did they all have contact with aliens while sleeping?
Because they have nightmares and hallucinations. Researchers say that the hallucinations in nightmares, that is, when you are half asleep and half awake, are extremely real, very real, and usually you can't tell the truth when you wake up. Moreover, the survey found that these people believed in the existence of aliens long ago, paid more attention to close encounters of the third kind's information in their daily lives, and longed for contact with aliens. The content of alien hair occupies a large proportion in their thoughts, so it is normal to have hallucinations related to aliens in nightmares, that is, thinking during the day and dreaming at night. Some people have nightmares and hallucinate, then go back to sleep and start dreaming. The content of the dream is probably information related to that illusion. For example, you have a ghost illusion, and the ghost finds you awake and leans over to you, and then what happens and starts a nightmare. Those surveyed dreamed of coming to an alien spaceship and a series of stories happened. ......
Through this story, we can understand why some people claim that they will see ghosts after they die, because there has always been a deep ghost culture in our China tradition. Ancient people's fear of the unknown was interpreted as ghosts, while modern people know ghosts through stories, books and movies they heard when they were children. Ghosts in these contents are usually more horrible. Over time, I am used to associating what I am afraid of with ghosts. So you will be afraid when you have nightmares, and then you will have ghost hallucinations.
Since ghosts have nothing to do with ghosts, how do you explain nightmares?
When people are sleeping, their brains are in a dormant state, and they will dream in half. Many people know that during sleep, deep sleep and shallow sleep alternate constantly. When the brain sleeps lightly, people will dream; When you are asleep, you are completely unconscious and feel that you are in the deep sea without light. Under normal circumstances, people wake up from a shallow sleep. When you wake up from a deep sleep, the possibility of having nightmares is very high. At this time, if you wake up but can't move, it's because the center responsible for receiving information in the brain is awake, while the center responsible for exercise is still asleep. At this time, you can only blink to vent, but you can't move, even if you miss bite the tongue. The explanation of nightmares is as simple as that, but it is no different from stroke patients. Because a part of the brain is still sleeping, and the awakened part continues to sleep under the influence, it will produce an irresistible feeling. In this process of half-dreaming and half-waking, what people think at this time is very easy to be projected into hallucinations, combined with the information transmitted by the retina, and transmitted to the signal processing center of people. Because the degree of truth is extremely high, even the brain is usually deceived.
Knowing the nightmare, I hope you don't feel too afraid of it, and don't leave any shadow in your heart because of the hallucinations caused by previous nightmares. I know so much because there are many such experiences, which are related to the irregular sleep in Dachuan, hehe. And because I hate the feeling of having nightmares, I must try my best to wake myself up when nightmares happen. It is not easy to do this. Let me tell you some ways to prevent nightmares first.
The main thing is to develop a healthy lifestyle and drink less water before going to bed. Don't force yourself when you don't want to sleep. Because you may have nightmares when you are asleep, but it seems that the probability of hallucinations is relatively low.
There are several ways to wake yourself up when you have nightmares. It is almost impossible to do things with your hands and feet in a nightmare, but you can try shaking your head. I have practiced shaking my head 90 degrees and moving my limbs slightly now. Also, don't sleep there motionless after waking up, you may have nightmares again. It's best to turn on the light and get up immediately, drink some water, sit down and go back to sleep when your mind is clear.
⑤ 1. TCM diagnosis
Nightmare refers to screaming or hallucinations during sleep, and the body is heavily pressed, unable to move, unable to breathe, panic, chest tightness and suffocation, which are common clinical symptoms. Its occurrence is related to physical weakness, fatigue, anemia, hypotension and emotional factors such as depression, anger and anger.
Because people's blood pressure is further reduced during sleep, it leads to cardiac and cerebral ischemia and reduced oxygen supply, and the motor center of cerebral cortex enters the inhibitory state before the sensory center; Or it is because peripheral nerves enter a state of inhibition faster than central nerves, resulting in nightmares of wakefulness and motor paralysis.
Traditional Chinese medicine believes that nightmares are caused by deficiency of both qi and blood, poor circulation of qi and blood, qi stagnation and blood stasis, and obstruction of meridians. Therefore, for the prevention and treatment of nightmares, we should first pay attention to strengthening nutrition, enhancing physical fitness, preventing excessive fatigue, treating anemia, and avoiding negative emotions such as depression, anger and anger. For patients with hypotension, 20 grams of Radix Astragali, Radix Codonopsis, Radix Angelicae Sinensis and Radix Glycyrrhizae can be decocted in water for half a month. Most patients can recover their blood pressure within a course of treatment.
In addition, the prevention and treatment of nightmares can still be guided. The specific method is to bend your thumb and hold it with the other four fingers. Especially when you fall asleep, you should form a habit and make unremitting efforts to gradually reduce the onset of nightmares.
2. Modern general psychological diagnosis:
A. From the perspective of child psychology:
Nightmares are common among children, most of whom are 3-7 years old. "Nightmare" refers to the content that can be vividly recalled after waking up from a nightmare. These dreams are always terrible, which makes the dreaming children in extreme anxiety, or played by monsters, or chased by bad guys and beasts, or they and their relatives are on the verge of some kind of disaster, and so on. At that time, they couldn't even think about it, and they couldn't escape. They were often helpless and out of breath. When I am about to wake up, I often feel that my body and limbs are hard to move, as if I were pinned down by something. It takes several struggles to fully awake.
Nightmares occur in rem sleep with dreams. Because rapid eye movement sleep accounts for a high proportion in the second half of the night, the frequency of nightmares is higher in the second half of the night. At that time, the heartbeat and breathing may be accelerated, but there will be no obvious spontaneous response. When children wake up from nightmares, they often cry and say they are afraid. Parents' comfort can calm them down and go back to sleep.
Psychologists have analyzed that most children had psychological contradictions and emotional anxiety before having nightmares, or they felt uncomfortable during sleep because they watched horrible TV and listened to horrible stories, such as their noses covered with blankets and their chests oppressed by quilts. Some children may have poor breathing due to a cold, or sleep discomfort due to intestinal parasitic diseases, or feel hungry or full, which may induce nightmares.
* * * The difference between nightmares and night terrors * * *
Night terrors have obvious frightened expressions, strange sounds and autonomic nervous symptoms, such as rapid heartbeat and breathing, sweating, dilated pupils and pallor, which shocked the parents of the children, but I know nothing and have no memory afterwards. A nightmare is when a dreaming child wakes up from a dream and feels very scared, but others can't see any obvious movement. The night scares others, and the nightmare scares yourself.
When a child has nightmares, you can wake him up as soon as possible and comfort him by saying, "This is a dream, not true, don't be afraid." Let him sleep until he is emotionally stable. Generally, medication is not required. Frequent attacks can be taken orally for several nights before going to bed. Avoid watching horror movies and listening to horror stories at ordinary times. Those with psychological pressure and physiological incentives should be treated symptomatically. After removing various factors that induce nightmares, they generally do not recur frequently. In addition, with the increase of age, the onset of nightmares will naturally decrease or stop.
* * * What's the difference between nightmares and night terrors? ***
Nightmare means waking up from a nightmare and vividly recalling the contents of the nightmare after waking up. These dreams are very terrible, which makes the dreamer in extreme anxiety, or playing with monsters, or being chased by evil beasts, or on the verge of some kind of disaster for himself and his loved ones ... At that time, he couldn't shout out, couldn't escape, and was often helpless and out of breath. When I am about to wake up, I often feel that my body and limbs are hard to move, as if I were pinned down by something. After several struggles, I was completely awake.
Nightmares occur in rem sleep with dreams. Because rapid eye movement sleep accounts for a high proportion of sleep in the second half of the night, it is easier to have nightmares in the second half of the night. When a nightmare occurs, the heartbeat and breathing may gradually increase slightly, but there will be no obvious autonomic nerve release response. Children often cry and complain about fear when they wake up from nightmares, and the comfort of adults can calm him down and fall asleep again. Adults often can't go back to sleep after waking up from nightmares, which affects their mood the next day.
The main points of clinical differentiation between nightmares and night terrors are as follows: the frightened expression, strange cries and autonomic discharges (rapid heartbeat and breathing, sweating, dilated pupils and pale face) of night terrors are extremely remarkable, which stunned onlookers, but I knew nothing about them and had no memory afterwards. A nightmare is when the dreamer wakes up from a nightmare and feels very scared, but others can't see any obvious movement. The night scares others, and the nightmare scares yourself.
* * * nightmare, how to do? ***
Dreams, everyone has done, strange: fishing, fighting, crying and laughing. However, dreams mostly come from our thoughts, memories and imagination. As the saying goes, "thinking day and night" makes sense. Of course, some night dreams are related to the sleeping environment.
Nightmares occur in the dreamy REM sleep stage, because REM sleep accounts for a higher proportion in the sleep after midnight, so nightmares occur more in the sleep after midnight. When having nightmares, the heartbeat and breathing may be accelerated, but there will be no obvious autonomic response. When children wake up from nightmares, they can describe the scenes and often say that they are afraid. Sometimes I cry and shout in my dreams, and my arms, legs and feet are kicked and beaten. Some children are very tired during the day and always want to sleep.
Psychologists have analyzed that most children have had psychological contradictions and emotional anxiety before having nightmares; Or it is caused by watching horror novels, TV, movies and listening to horror stories; Or sleep discomfort caused by intestinal parasitic diseases, or hunger and satiety. Of course, some nightmares are related to the sleeping environment. For example, the room is too hot, too dry or the sleeping posture is not suitable, such as hand pressing on the chest affects breathing, drinking too much water before going to bed, bladder swelling, etc., and having some nightmares.
When a child has nightmares, parents should wake him up as soon as possible and comfort the child by saying, "This is a dream, not true, don't be afraid." Don't let the child fall asleep until his mood is stable. Generally, medication is not required. If the child wakes up from a nightmare, his heart rate and pulse are accelerated, and the attack is generally 1 min. It is difficult to wake up in the early morning after the attack, often accompanied by sleepwalking. This disease should be distinguished from nocturnal epilepsy. You should see a neurologist for help as soon as possible.
Frequent nightmares are mostly due to physical and mental fatigue, excessive excitement, anxiety, emotional tension or being spoiled before going to bed. Please go to the psychological counseling clinic for psychotherapy. Under the guidance of a child psychologist, you can take a small amount of sedatives, such as diazepam, 0.2 mg/kg for children, for several nights before going to bed. You should avoid watching horror movies and listening to horror stories. Those with psychological pressure and physiological incentives should be treated symptomatically. After removing all kinds of factors that induce nightmares, they generally do not have frequent attacks. In addition, with the increase of age, the onset of nightmares will naturally decrease or stop.
B. Psychology and medicine
Nightmare is a dream experience occupied by anxiety or fear, which patients can recall in detail afterwards. Common in REM sleep, vivid and clear memory, slight physiological activation. It usually appears after midnight when rapid eye movement sleep increases, and it is more common before the age of 20. It is characterized by nightmares during sleep, intense dream experience, often accompanied by autonomic nerve excitement symptoms such as emotional tension, palpitation, cold sweat and mild pallor. Sometimes it feels difficult to move after being pressed, and it is necessary to struggle to wake up. Nightmare experiences are very vivid and usually involve topics that threaten survival, safety or self-esteem. After waking up, you can describe the dream experience in detail immediately or the next morning and communicate with others.
Nightmares generally don't need special treatment. People with frequent attacks should understand their psychological factors, give targeted psychotherapy, and further check whether there are cardiovascular diseases, asthma and digestive tract diseases, and take small doses of benzodiazepines when necessary? FDD6？ Drugs.

Nightmares are nightmares. As far as the word "Yan" is concerned, Xu Shen said in Shuo Wen Jie Zi: "Yan is also a dream."

C. Others
The so-called "ghost pressure" is definitely not a ghost pressure on the bed, let alone haunted. In fact, it is a disease of sleep disorder. The phenomenon of "ghost crushing the body" belongs to a symptom of sleep paralysis in sleep neurology. At this time, the patient is half awake and half asleep, and the amplitude of brain waves is also awake. Some people will also have hallucinations, but the muscle tension of the whole body is reduced to a minimum, which is similar to the "paralysis" state, and the whole body can't move, just like being put on a golden bell jar, which is what most people call it.
Patients with "cataplexy narcolepsy" suffer from "ghost crush" most often. Such patients can fall asleep at any time, showing a state of being half awake and half asleep at any time, and often have "sleep hallucinations" and dream of strange people, things and things. When the patient is awake, whenever he is excited, laughing or angry, he will suddenly feel weak and fall down.
Our sleep cycle is from sleep period, shallow sleep period, deep sleep period, and finally into "rapid eye movement period" (dreaming period). Sleep paralysis is mainly due to the early appearance of rapid eye movement, which leads to the inconsistency of rapid eye movement stage. In fact, in the rapid eye movement stage, the body is essentially at rest, and the connection signal with the brain is temporarily interrupted. This is a defensive measure, so that the human body will not realize the dreams in real life. For example, when dreaming of hitting people, it will not really act, and it will not punch and kick people at the bedside.
When the sleep nerve is paralyzed, the brain recovers from sleep rest, and it is too late to reconnect with the body, leaving people in a state of half sleep and half waking, and dreams and realization are intertwined, resulting in disharmony between the body and the brain. At this time, the muscle tension of the whole body is the lowest, so it will cause the situation that I think about it, but I can't get up: I want to exert myself, but I can't exert myself. This is the most common situation of "ghost pressing the bed".
Generally speaking, under the circumstances of excessive pressure, anxiety, tension, extreme fatigue, insomnia, lack of sleep or jet lag, sleep will enter the rapid eye movement stage (dreaming stage) ahead of time, and there will be a situation of "ghost pressing the bed"-sleep paralysis. This happens to people of any age, mostly in adolescence, and few people happen continuously. Unless it happens frequently, you need to seek the help of a sleep doctor. As long as you know this symptom, you don't have to worry too much.
If a person has palpitation or palpitation during the day, there are two main feelings: one is the feeling of being chased caused by tachycardia (Chinese medicine has: tachycardia, if it looks like a person, it will be caught); One is the feeling of suspense caused by bradycardia or premature beats. Therefore, people who are prone to palpitations will have nightmares of being chased at night (occasionally causing dreams of chasing others) and people hanging and falling. If people have transient cerebral ischemia during the day, they will have terrible symptoms such as dizziness, palpitation, chest tightness, black eyes, tinnitus and various neurological disorders. Therefore, people who are weak and prone to cerebral ischemia, people who have excessive fears, people who take quinidine and cause hypotension, and people who suffer from neck flexion and poor blood flow due to excessive pillows or improper sleeping posture during sleep will have a terrible nightmare called a nightmare in medicine when they sleep deeply at night. Shallow sleep can cause inexplicable panic, which is also commonly known as ghost pressure. Sometimes, people wake up from cerebral ischemia, and the visual and motor disorders that last for a few minutes are not over, which can also cause people to struggle to wake up, but they can't wake up. For example, there is a "haunted" bed in the countryside, which can make people have nightmares every night, which is caused by the high pillow. Because the nightmares or ghosts during sleep are mostly related to the neck flexion oppression caused by the high pillow or improper sleeping position during sleep. Therefore, there is scientific basis and it is really effective to try to move the neck to improve the ghost in the case of nightmares or ghost pressure. Patients who often have nightmares or have ghost body pressure may wish to give it a try. When people are highly nervous during the day, they will be scared by very small sounds. People sometimes have nightmares because they suddenly seem to hear some kind of loud noise during the process of constantly changing their sleeping positions because of mental stress. This loud noise is obviously caused by the friction between the ear and the pillow when people change their sleeping positions. This kind of "loud noise" that has been neglected for a long time during sleep sometimes becomes very terrible when you are nervous. Abnormal heartbeat or cardiac function during the day can cause cerebral ischemia, and abnormal heartbeat or cardiac function at night can also cause cerebral ischemia. The specific dream is a simple palpitation nightmare of being chased or falling in the air, and then a nightmare (namely cerebral ischemia) occurs. For another example, sleeping pills can treat the nightmares of neurasthenia patients, because the nightmares of such patients are caused by tachycardia. Sleeping pills can slow down the heartbeat, but the slow heartbeat sometimes causes cerebral ischemia in people with low blood pressure. So sometimes using sleeping pills to treat nightmares is not only ineffective, but will aggravate the patient's condition (unfortunately, almost all doctors in China are still using sleeping pills to treat nightmare patients, regardless of the specific cause). Because the blood vessels around heaven and man expand more in summer than in winter, the blood pressure of heaven and man in summer is lower, and it is more prone to cerebral ischemia (for example, people who stand for too long or squat and suddenly stand up are prone to cerebral ischemia). Therefore, people are more likely to have nightmares or ghosts when they sleep in summer. In addition, people will have cerebral ischemic syncope due to strong fear during the day. When people are sleeping, they will also have nightmares or ghosts because of dreams of strong fear caused by simple palpitations. When people have transient cerebral ischemia during the day, they will only have terrible symptoms such as dizziness, palpitation, chest tightness, black eyes and various neurological disorders. In severe cases, there will be symptoms such as sweating, pallor, dilated pupils and even fainting due to loss of consciousness. When people have transient cerebral ischemia during sleep, the same mild symptoms will only produce terrible dizziness, palpitation, chest tightness, black eyes and various neurological disorders. In severe cases, there will be symptoms such as sweating, pallor, dilated pupils and even loss of consciousness.
In short, everything experienced in dreams is what people think or experience during the day. No one will feel mysterious and afraid because he suddenly thinks of a person who has been dead for many years during the day, so there is no need to feel mysterious and afraid because he suddenly dreams of a person who has been dead for many years. Similarly, no one will feel mysterious and special fear because of various palpitations during the day, and there is no need to feel mysterious and special fear because of sudden nightmares of various palpitations. Of course, if a person often has nightmares, first of all, it is necessary to find out whether the physiological symptoms after waking up from nightmares also exist during the day. If there are such physiological symptoms during the day, then it is certain that this nightmare is caused by my psychological and physiological abnormalities, and I should go to see a doctor further. If this physiological symptom doesn't exist at all during the day or the psychological physiology is completely normal, then you can be sure that this nightmare is caused by abnormal sleeping position. You don't need to see a doctor again, just pay attention to your sleeping position.
