How do Chinese medicine think dreams are formed?

According to the theory of traditional Chinese medicine, Yang entering Yin leads to insomnia, and Yang leaving Yin leads to insomnia. When Wei Qi enters Yin, the body surface temperature drops, and people go to sleep. But yin dominates quietness and yang takes the initiative. The proactive nature of Weiyang hiding in the shade will not change. When weiyang yang enters yin, yin and yang are relatively stable.

Although Weiyang tried to break through the control of Yin, it did not cause qualitative change, so the situation that Yin and Yang embraced and never left did not change. At this time, most people were asleep, and there were few dreams. With Weiyang constantly accumulating strength, at a certain stage, both the power to control the Yin point and the power to rush out of Weiyang are struggling, and the calm situation of Weiyang hidden in the Yin point is broken, resulting in the situation of opposition and struggle between Yin and Yang, and people enter dreamy sleep until Yin controls Weiyang to rush out again, and Yin and Yang reach a new relatively stable period, and the dreamy moment comes to an end. After a period of energy accumulation and preparation, the human body began to fight yin qi again. This time, the preparation time is shorter than the last time, and the struggle between Yin and Yang is longer, so the dream time is naturally longer than the first dream period. After repeated several times, the relative stability period of Yin and Yang is getting shorter and shorter, and the confrontation period is getting longer and longer. Until the end, the power of Yin can no longer control Weiyang, Weiyang finally rushed out of the embrace of Yin, and people also woke up. The last confrontation between Yin and Yang took the longest time and was the most intense, so the dream took the longest time and had the strongest impression. Most of the dreams that people can recall and remember are dreams of this period.
