People dream all their life, and there are no people who don't dream. Although there are a large number of descriptions of dreams in literary works at all times, at home and abroad, such as the famous ancient opera Peony Pavilion and Cao Xueqin's dream of Red Mansions, what is the source of dreams?
The more rigorous scientific research on dreaming began in the 19th century
Through the above statements, we can conclude that dreams are the result of the forced opening of the subconscious due to physical or psychological pressure (human instinct and the role of the subconscious).
Why do people dream

Scientists observed the whole sleep and came to the following conclusions:
(1) Both normal sleep and abnormal sleep are necessary for people's health. If abnormal sleep is deprived, people's mental activities will be affected and even psychosis will occur; (2) EEG records showed that high amplitude slow waves were the main manifestation in normal phase sleep, and single or discharge discharges were found in heterogeneous phase sleep. The records of eye movement descriptor showed that the eyes in the sleep were rarely rotated or only rotated very slowly, and the eyes rotated rapidly 50-60 times per minute during heterogeneous sleep;

(3) A positive investigation sleep period is about 80-120 minutes, and heterogeneous sleep is 20-30 minutes. The two kinds of sleep alternate with each other, calculated as 8 hours per night, alternating about 4-5 times; (4) Dreams only occur in the heteromorphic sleep period, and the normal sleep period is the deep sleep period. Some people have done such experiments. By observing the EEG and eye rotation of sleepers, they wake up the subjects in normal phase sleep and heterogeneous sleep respectively. As a result, the subjects in normal phase sleep said they had not dreamed, and 85% of the people in heterogeneous sleep said they were dreaming and could recall the dreams they had at that time. Since everyone dreams and dreams every night, why can you remember dreams sometimes, but not sometimes? This mainly depends on which sleep period you wake up from. For example, if you wake up from heterogeneous sleep, you can clearly answer the book and dream; If you wake up from normal sleep, you can't recall your dreams.

(2) The content of dreams is related to people's physical condition. Patients with neurasthenia are often in a state of virtual hyperactivity due to the decline of inhibition in the cerebral cortex, which is easy to produce anxiety and tension. Therefore, most dreams are dreams of bad structure or fear. Some people dream that their chest is pressed by a big stone, so that they can't move, can't breathe and can't shout. When they wake up, it turns out that their hand is pressed on their chest. Another example is a child with enuresis, who dreams that he is eager to urinate and find the toilet. It is not easy to find it. He can urinate, and only after waking up can he find that he has wet the bed. In fact, such dreams are related to the defecation caused by bladder fullness. At this time, children can't wake up in time, so they wet the bed. Therefore, dreams are completely a physiological and psychological phenomenon.
