Nightmares are caused by transient cerebral ischemia during sleep. When transient cerebral ischemia occurs during the day, people 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, when people have nightmares or ghost beds, they can lift the ghost's body by trying to move their necks, which has scientific basis and effective methods. Patients who often have nightmares or have ghosts may wish to have 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.
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.
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.

Usually, nightmares are partly caused by incorrect sleeping posture. For example, when sleeping, putting your hand on your chest and pressing your heart, you will unconsciously feel difficult to breathe and form nightmares. Sleeping on your back and lying flat at the same time can also easily cause nightmares. Therefore, the sleeping position when sleeping is very important.
