Phenomena that science cannot explain.

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.

Dreams are a way to coordinate the balance of human psychological world.

Because the right hemisphere is dominant when dreaming and the left hemisphere is dominant after awakening, the dynamic balance between nerve regulation and mental activity can be achieved by alternately waking up and dreaming during the 24-hour day and night activities of the body. Therefore, dreams are a way to balance people's psychological world, especially for people's attention, emotions and cognitive activities.

Dreamless sleep is not only of poor quality, but also a sign of brain injury or disease.

Recent research results also confirm this view, that is, dreams are the result of the brain's regulatory center balancing various functions of the body, and dreams are the need for the healthy development of the brain and maintaining normal thinking. If the brain's regulatory center is damaged, dreams will not form, or only some incomplete dream fragments will appear. If you sleep for a long time without dreams, it is worth people's vigilance. Of course, if you have nightmares for a long time, it is often a sign of weakness or some diseases.

Depending on Freud's dream analysis,

Dream is a subjective experience, an imaginary image, sound, thinking or feeling produced by people during sleep, which is usually involuntary. The scientific discipline of studying dreams is called the study of dreams. Dreaming is related to rapid eye movement sleep, which is a shallow sleep state in the later stage of sleep. It is characterized by accelerated eye movement, stimulation of pons, accelerated breathing and heartbeat, and temporary limb paralysis. Other sleep periods may also dream, but rarely. Lack of sleep when entering deep sleep is considered to be related to dreaming.

Dream is an image language. These images range from ordinary things to surreal things; In fact, dreams often inspire artistic and other inspirations. The forms of dreams include unpleasant nightmares and spring dreams that may accompany wet dream.

Most scientists believe that all human beings dream and sleep at the same frequency every time. Therefore, if a person feels that he has never dreamed or only had one dream in one night, it is because his memory of those dreams has disappeared. This kind of "memory erasure" usually occurs when a person naturally and gently enters the slow-wave sleep stage from the rapid eye movement sleep stage and enters the awake state. If a person is awakened directly from REM sleep (for example, by an alarm clock), they are more likely to remember the dreams they had during REM sleep (but not all the dreams that happened during REM sleep will be remembered, because a slow-wave sleep period will be inserted between each active sleep, which will lead to the memory of the previous dream disappearing).

True dreaming has been directly confirmed only in humans, but many people think that dreaming may also happen to other animals. Animals have been proved to have REM sleep, but their subjective experience is difficult to determine. The animal with the longest average REM sleep time is pangolin. Mammals may be the only dreamers in nature, or at least the most frequent dreamers, because it is related to their sleep patterns.

Some people think that the above explanation of dreams is unscientific. Dreams are just a kind of psychological activity when people are sleeping. The psychological activity in dreams, like the psychological activity when people are awake, is a reflection of objective things in the human brain. The bizarre dream in the dream is the illusion of stimulating various objective things when people are unconscious during sleep. For example, when people are awake and tachycardia, it seems that the palpitation feeling of being chased becomes a bizarre nightmare of being chased, and when people are awake and bradycardia or premature, the palpitation feeling becomes a bizarre nightmare of being hung and falling. In dreams, we often feel slight physiological symptoms that some people can't easily feel when they are awake, which is caused by the fact that the stimulation of external objective things is relatively small, while the stimulation of internal objective things is relatively strong.
