People have always tried to explain the meaning of dreams, so the Chinese folklore has “The Interpretation of Dreams” and the West has “The Analysis of Dreams”, and there are many different opinions. Dreams are one of the components of sleep. Without sleep, we cannot talk about dreams, and dreams and sleep go together. We cannot choose the subject of our dreams, whether they are wonderful or sinister. But how exactly does the brain form those uninhibited dreams? Although scientists have done a lot of research, no one has been able to clarify the nature of dreams so far, and little is known about the details of dreams. The current accepted view is that human sleep is always in a regular cycle, that is, in the alternation of fast-wave sleep and slow-wave sleep, and dreams are a manifestation of fast-wave sleep, in which the blood flow to the cerebral cortex increases and the oxygen consumption also increases. This means that although people are in sleep, some areas of the cerebral cortex are still in a state of intense activity, and dreams occur at this time of “turmoil”. According to the theory of Chinese medicine, the operation of the body’s Wei Qi is related to the rhythm of sleep, and Wei Qi is Yang. When Wei Qi enters Yin, people go to sleep. When Wei-Yang enters Yin, Yin and Yang are in relative stability. Although Wei-Yang tries to break through the control of Yin, it does not cause a qualitative change, so the situation of Yin and Yang holding each other and not leaving each other does not change, and people are in the stage of sleeping with less dreams. But Yin is the master of static and Yang is active. The active nature of Wei Yang, which is latent in Yin, will not change. As Wei Yang keeps accumulating strength, at a certain stage, the control of Yin and Wei Yang fight against each other to break out of Yin, and the calm situation of Wei Yang latent in Yin is broken. After several such repeated cycles, the relative stability of yin and yang becomes shorter and shorter, while the confrontation period becomes longer and longer, until finally the power of the yin component can no longer control Wei Yang, and Wei Yang breaks out of the Yin component’s embrace, and the person awakens. The last confrontation between yin and yang is the longest and most intense, so the dreaming time is also the longest and the dream gives the strongest impression, and most of the dreams people can recall and remember after waking up are the dreams during this period. This is in line with modern research on sleep cycles. There are many reasons for dreaming, and the theory of traditional Chinese medicine believes that there are five divine and spiritual (i.e., mental functions) in human, which are hidden in the five organs, as Suwen? The theory of Chinese medicine is that there are five human spirits (i.e. psychological functions), which are stored in the five viscera, as stated in Suwen (Suwen?) and Xuanming (Xuanming): “The heart hides the spirit, the lung hides the spirit, the liver hides the soul, the spleen hides the intention, and the kidney hides the will. The content of dreams also has some correlation with age and gender, such as children’s dreams are generally very short, simple, and most of the activities in dreams are their familiar environment and characters, etc. As they grow older, when they reach puberty, the strange contents in dreams also start to increase due to physiological changes affecting psychological changes. The elderly are relatively deficient in qi and blood, and participate relatively less in external social activities, so the dreams are mostly based on memories, which are related to the events of the people they have experienced. Women have a lot of emotional changes, emotional diseases, and are easily affected by physiological changes such as menstruation and pregnancy, so the content of dreams is richer in emotional tones, often with frightening content. Usually, dreaming at night does not require drug treatment, but if you seem to sleep overnight, dream disturbance, and have obvious symptoms of discomfort during the day, such as fatigue, dizziness, dizziness, panic, concentration, etc., then you should go to a specialist insomnia clinic for treatment. Then, according to the different physical types, clinical manifestations and dialectical typology of the patient, the rules and prescriptions such as nourishing the heart and tranquilizing the mind, calming the liver and nourishing the kidney and regulating the mind should be adopted respectively.
