More rigorous scientific research on dreaming began in17th century. 1886 Robert, an expert on dreams, believes that people are exposed to countless information intentionally or unintentionally in their daily activities, and they must release some of these information through dreams. This is the famous theory that "dreaming is to forget", which began to be popular again in the1980s one hundred years later. Shortly after Robert, Freud's theory of psychological dream interpretation appeared again. Freud believed that people constantly have desires and desires, which are expressed and released through various disguises and deformations in dreams, so that they will not break into people's consciousness and wake people up. That is to say, dreams can help people eliminate those desires and desires that are unacceptable to the conscious system and are the guardians of sleep protection. Freud's theory was popular from the beginning of this century to the 1960s. Later, the study of dreams in the world slowly left the field of psychology and entered the biological laboratory. Since then, dreaming has been regarded as a biological phenomenon. Michelle, a neurobiologist at the Lyon Dream Research Laboratory in France? Wei Ru is an internationally renowned expert in dream research. Wei Ru defined dreaming as "parasomnia" in 1959. He found through EEG test that people have 5 ~ 20 minutes of dreamy sleep every 90 minutes, and the signals reflected on the instrument screen are different, showing the changes of brain activity during sleep. If the subject is awakened when the EEG shows dreamless sleep, he will say that there is no dream; If you wake him up when he shows dreamy sleep, he will remember the dream he just had. In addition, the researchers used X-ray tomography technology to test and found that the image of the brain in dreamy sleep stage is close to that in waking state. Interestingly, the researchers found that dreaming is not unique to human beings, and birds and all mammals also dream. In the late 1970s, a scientist discovered through experiments on mice that dreamy sleep was also related to memory. Dreamy mice can remember their experiences better than those deprived of dream sleep, but the results of this study are not applicable to humans, because doctors use an inhibitor called monoamine oxidase when treating patients with mental depression, which can completely cancel people's dream sleep, but will not cause memory impairment. Wei Ru, a French expert on dreams, believes that dreams are determined by genetic factors. He compared the letters and numbers emitted by mice during their dream sleep and found that mice with the same genetic system had similar letters and numbers. A recent experiment by Bulga, a researcher at the University of Colorado in the United States, confirmed this theory. Bulga studied identical twins and found that twins who were raised by two different families in different places after birth actually had similar dream experiences, which proved that human dream performance is genetic memory.
In addition, there is a recent report on dreaming research in the just published American Science Weekly. The author of this report, a cooperative team of the Washington Institute of Neuroscience and the National Institute of Health in Bocaistar, Maryland, tested more than a dozen people who accepted the experiment with a high-performance neural tomography camera and found that the blood circulation in this specific area of their cerebral cortex was abnormally accelerated during the dream sleep stage. The researchers found that the visual nervous system responsible for seeing dream scenes and external visual scenes in the brain originally existed independently. According to the report, after seeing that the internal visual system of dreams has been proved to exist independently, it can explain why we have inflated emotions in dreams and why we can accept unreasonable eccentric plots and chaotic concepts of time and space.
Dreaming is a normal and indispensable physiological and psychological phenomenon of human body. After people fall asleep, a small number of brain cells are still active, which is the basis of dreaming. Why do people dream and what happens if they don't dream?
Normal dream activity is one of the important factors to ensure the normal vitality of the body.
Scientists have done some experiments to stop people from dreaming. That is to say, when the sleeper has a dream brainwave, he is immediately awakened to stop his dream from continuing, and so on. The results show that deprivation of dreams will lead to a series of physiological abnormalities of human body, such as blood pressure, pulse, body temperature and skin electrical response ability, and the function of autonomic nervous system will be weakened. At the same time, it will also cause a series of adverse psychological reactions, such as anxiety, tension, irritability, perceptual hallucinations, memory disorders, irritability and so on. Obviously, normal dream activity is one of the important factors to ensure the normal vitality of the body.

Is it accurate to dream during the day? Duke Zhou doesn't allow it. Dreaming is normal and the pressure is too great.
What's it like to dream during the day? Duke Zhou's dream is actually an explanation and deduction of the outside world (touch, sound, etc.). When some functions of the brain are turned off during sleep. Compared with daytime, dreams are often discontinuous and unreasonable, because only a small amount of memory and understanding functions are retained at this time.
People can't perceive the existence of the outside world when they sleep, and they will have different degrees of tension, so the mood accompanying dreams is even more tense and even nightmares. The problems that you are concerned about recently, with the opening of your mind, will be easier to enter your dreams. This is the so-called thinking day and night.

What do you mean by dreaming during the day? It's normal ... I'm usually too tired. Pay attention to rest.
Why do you dream when you sleep during the day? While sleeping, each of us had a dream. The content of dreams is very strange, and some people often give it a layer of superstition and mystery. So why do people dream? What is the dream?
People usually work and study during the day and sleep at night. Sleep can be divided into slow-wave sleep and heterogeneous sleep. People fall asleep in the first 70- 120 minutes, which belongs to slow wave sleep. Heterogeneous sleep is a periodic state of excitement during sleep, often accompanied by eye movements, limb and facial muscle twitching. Heterogeneous sleep lasts about 5- 15 minutes, then turns to slow-wave sleep, and so on.
During the whole sleep process, such repeated conversion is 4-6 times. As far as the whole sleep time is concerned, slow-wave sleep accounts for about three quarters, and heterogeneous sleep accounts for about one quarter. People's dreams always occur in heterogeneous sleep stage, so in one night's sleep, they will probably have 3-5 dreams. Moreover, it is often the dream in the last heterogeneous sleep that recalls the content of the dream. 〕
The source of dreams mostly comes from something in our subconscious, from our thoughts, memories and imagination, which is what people often say "thinking day and night".
Under normal circumstances, proper dreaming is harmless to people and also helps to restore physical strength and energy. But dreaming too often will affect the quality of sleep.
Why do people dream during the day? According to relevant data, people spend about two-thirds of their lives sleeping and one-fifth dreaming. If a person lives for 75 years, he will dream for 15 years.
Why do people dream? As the saying goes: I think during the day and dream at night. The root of dreams is the activity of the brain. In most sleep processes, brain waves, eye movements, etc. The same as when I woke up, but my body muscles were in a state of inhibition. People change from shallow sleep to deep sleep, dreamless sleep lasts 1.5 hours, and then dreamless sleep occurs. There will be 1.5 hours of dreamless sleep in the future. Dream sleep in the early morning is longer, so I usually dream more in the morning.
Generally speaking, healthy young people engaged in manual labor are easy to fall asleep at night and have fewer dreams; And some people who are engaged in mental work and are in poor health, when they sleep at night, some brain cells are excited, so they dream more; Patients who often suffer from insomnia or stay in bed for a long time have strange dreams every night because their brains are hard to rest.
The content of dreaming is often related to * * * during the day or during sleep:
1. If you think too much about something during the day, you will dream at night; Some people never think about someone or something during the day, but because they have experienced it before, some brain cells will recall the past when they sleep at night, so they will dream.
2. When sleeping, the external * * * will make the brain react incorrectly, thus having all kinds of weird dreams. For example, when children fall asleep, they often kick off the quilt and feel cold, and then they often dream that they are walking in the snow. When he sleeps with his hands on his chest, he will feel forced to breathe and his heart will beat faster, and then he will often have all kinds of nightmares.
3. The * * * and pathological changes of various organs in the body will cause similar scenes in dreams. If you are in a hurry, you will dream that you can't find the toilet anywhere; Some people have loose bowels and dream of a stomachache at night. Wait a minute.
Does dreaming affect physical health and brain thinking?
Generally speaking, dreaming more will reduce the quality of sleep and affect daytime work. Dreamy sleep is easy to induce gastric ulcer, angina pectoris and asthma.
Some people take sleeping pills before going to bed in order to dream less and ensure the quality of sleep. In fact, this can only produce some effects in a short time. If they take a lot of sleeping pills for a long time, the dreamless sleep time will be shortened with the decrease of dreamless sleep, which will only aggravate insomnia.
So don't dream, okay Facts have proved that dreamless sleep can rest the brain, and dreamless sleep can rest the body; Dreaming also helps to consolidate memories. And people who don't dream often may suffer from sleepwalking, night terrors, grinding their teeth, talking, nocturia and other diseases. Snoring often occurs in dreamless sleep, but dreamers generally do not have the above distress.
What is dreaming during the day? Sleep is a habit to a great extent, so keeping good physiological habits and following the natural laws of sleep is the best way to prevent sleep disorders. The medicine should be taken under the guidance of an experienced doctor. At the same time, we can do the following: ① Develop good work and rest habits and relax before going to bed. Don't be too hungry and full before going to bed. ③ The light in the bedroom should be soft and the temperature should not be too high. ④ Insist on washing feet with hot water before going to bed every day. ⑤ Eat more sunflower seeds, jujube, honey, millet, milk, etc. Diet, drink millet, lotus seeds, red dates and lily porridge at night. Try not to drink tea, coffee or coke after noon. Don't drink before going to bed. Although alcohol may make people fall asleep quickly, it will also disrupt the sleep rhythm and affect physical recovery. 8 Don't smoke: Nicotine prevents people from going to sleep smoothly, which affects the quality of sleep. Even a small amount of smoking before going to bed has an impact on sleep. In addition, I suggest that you use TCM to treat syndrome differentiation, regulate qi and blood, adjust the function of viscera, and choose methods such as calming the nerves, nourishing yin and tonifying the kidney, strengthening the spleen and purging the liver, promoting blood circulation and removing blood stasis to let yourself sleep well.
What's the difference between dreaming during the day and dreaming at night? The dreams we have during the day are usually called daydreams. At that time, we usually didn't sleep. We can be said to be interesting at this time, but at night, we dream in the shallow sleep stage of sleep. Our thoughts at this time can be said to be unconscious or implicit. I can't control what we think and do, so the content of dreams is sometimes inexplicable and ridiculous, but during the day, it is different. Sometimes we think about irrelevant things. We can all say that we are daydreaming.
I think during the day and dream at night. Why do you dream?
Dream is a strange phenomenon, and the experience of dreaming is also owned by people.
Psychological explanation of dreams: Dreams are spontaneous psychological activities at a certain stage of human consciousness during sleep.
In this kind of psychological activity, the whole process of individual physical and mental changes is called dreaming. In a typical night sleep, the average person's first dream appears about 90 minutes after falling asleep.
The duration of the dream is about 5- 15 minutes (average 10 minutes). During the whole night's sleep, dreams appear in cycles at all stages of sleep.
And about 4-6 dreams a night; Total * * * about 1-2 hours of sleep time, is in a dream.
what is dream
Dream is a strange phenomenon, and the experience of dreaming is also owned by people.
However, in human culture, the understanding of dreams has always been a mystery, regardless of ancient and modern times. In underdeveloped tribal societies, dreams are often regarded as instructions from God or worshipped by the devil, which is not surprising.
Even in modern civilized society, there are still many superstitions about dreams.
There are many stories about dreams in the cultural refinement of our country.
Such as: Zhuang Sheng Meng Die, Meng Ke, Meng Ke, Cai Ji, Meng Ke, etc. They are all dream stories that people have been talking about.
However, China and the West seem to have different views on dreams from ancient times to the present. The Greek philosopher Plato once said: Good people dream, and bad people do evil.
On the other hand, China's ancestors thought there was no dream. To people, saints also; It means that saints have no delusions, so they don't dream.
Judging from the scientific research results of dreams in psychology today, there are many misunderstandings about dreams in ancient China and the West.
According to the research of psychologists, there is no distinction between good people and bad people, and there is no distinction between sages and fools. Everyone dreams, even animals dream.
Because, when animals sleep, their eyes will also beat rapidly (there is a chance to observe the dog's sleep). The difference is that animals can't talk in their sleep like people after waking up. The general explanation of the so-called dream in psychology is that the dream is a spontaneous psychological activity produced at a certain stage of consciousness during sleep.
In this kind of psychological activity, the whole process of individual physical and mental changes is called dreaming. 1.
In a typical night sleep, the average person's first dream appears about 90 minutes after falling asleep.
The duration of the dream is about 5- 15 minutes (average 10 minutes). During the whole night's sleep, dreams appear in cycles at all stages of sleep.
And about 4-6 dreams a night; Total * * * about 1-2 hours of sleep time, is in a dream. 2.
I have 4-6 dreams every night. Why can I only remember a few dreams when I wake up? On this issue
There are three different views: one is the view of interference theory: several dreams interfere with each other and new dreams come into being.
Interfere with previous dreams; Although dreams come again and again overnight, when I wake up in the morning, I probably only remember the last dream before I wake up.
This explanation is generally consistent with the experience of ordinary people.
Second, the viewpoint of motivation forgetting theory: dreams are mostly unpleasant things, and the parties don't remember them to avoid anxiety. This explanation does not conform to the general facts.
Because, in fact, the dreams that most people remember are not all pleasant things.
Third, the viewpoint of information service theory: dreaming is completed in a short time, which is essentially short-term memory.
Short-term memory is not reviewed, long-term memory is not stored, and it will naturally be forgotten soon.
This is a new explanation method since the rise of cognitive psychology, which seems more reasonable.
