Why do people have some bizarre dreams?

Chinese medicine believes that human consciousness (that is, psychological function) is composed of five parts. These five parts are stored in the five internal organs, which is the so-called "five records". "Five Qi Articles of Su Wen Xuan Ming" said: "The five zang-organs store the mind, the lung stores the spirit, the liver stores the soul, the spleen stores the meaning, and the kidney stores the will, so it is hidden by the five zang-organs." Five notes of dirty images are the theoretical basis of Chinese medicine dream interpretation, and five notes of dirty images can interpret dreams. Mainly, the change of five records is the internal cause of dreams. Seven emotions, evil spirits and internal and external stimuli are the inducing factors of dreams. People with seven emotions have seven emotions, which is a normal psychological activity of human beings. The seven emotions have great influence on the balance of Yin and Yang, the movement of Qi and blood, the function of zang-fu organs and the patency of meridians. Traditional Chinese medicine believes that seven emotional processes, including joy, anger, worry, thinking, sadness, fear and shock, summarize people's main psychological activities. They belong to the heart, liver, spleen, lung and kidney respectively, just like the "Five Zhi", which is the emotional expression of the qi of the five internal organs. Disorder of yin and yang of zang-fu organs and disorder of qi movement can be manifested as changes and abnormalities of seven emotions. Similarly, the change and abnormality of the seven emotions will inevitably lead to the imbalance of Yin and Yang, the disorder of Qi and blood, the dislocation of the five senses, and even directly damage the viscera and their organs. Under normal circumstances, it will not lead to dreaming, but strong emotional fluctuations will lead to dreaminess. Among the above seven emotions, thinking, anxiety, shock and fear lead to many dreams, so the ancients have the saying of "thinking day and night". The external causes of pathogenic factors include normal environmental stimuli and pathogenic factors, which invade the human body from the outside and do not belong to the corresponding zang-fu organs. Instead, they wander around the whole body with the operation of the camp-guard qi, causing the five gods to be out of place, which makes people restless and have dreams. Apart from the six evils (wind, cold, summer, dampness and fire dryness), all factors (evil spirits) that can cause human diseases, such as phlegm-dampness, blood stasis, plague, house fatigue, diet, trauma, insect accumulation, etc., may affect the yin, Yang Qi and blood of viscera, thus inducing dreams. In vivo and in vitro stimulation includes many aspects, such as seasonal exchange, climate, heat and cold, sound, smell, geographical location, sleeping position and so on. Internal stimuli include hunger, retention of urine and feces, thirst, dry throat, sweating, nocturnal emission, menstruation, etc. There are seasonal and climatic factors in external stimuli, and there are also stimuli that the body receives during sleep. For example, when the weather is cold, there will be many sad dreams; In windy weather, you will dream of flying. Physical stimulation factors, such as falling asleep with something in your arms, will dream that you want to talk but can't make a sound; Sleeping in pajamas, sometimes dreaming about snakes; Women curl their hair with a curling iron before going to bed, and sometimes dream that their hair hangs on a branch. Some dreams are not caused by physiological and psychological factors, but by factors that appear in the sleeping environment, which lead people to have different dreams. The content of dreams is related to the stimuli felt by the sensory organs during sleep. When sleeping, stimuli from inside or outside the body are transmitted to the central nervous system, which often produces false feelings, which are inconsistent with the actual situation and become dreams. Such as the whistling wind and the ticking rain, you will dream of "asceticism in the rain". Therefore, seven emotions, evil spirits and internal and external stimuli can induce dreams and are the trigger points of dreams. At the same time, it also affects the generation of dream content to a certain extent. Modern medicine believes that dreams are caused by various stimuli that act on the specific cortex of the brain during sleep, including the traces of primitive excitement left in the brain. Various stimuli, psychological, physiological, pathological and environmental factors will affect the formation of dreams. Such as hunger, defecation, pain, hypoxia, parasitic activities and thinking and emotional activities. Sleep is an alternating process of slow wave phase and fast wave phase. Dreams mainly occur during fast-wave sleep, and some exciting foci in the cerebral cortex are still active. However, the connection between these excited brain cell groups can no longer be carried out normally, so the content of dreams is often bizarre. It turns out that people in slow-wave sleep say "no dreams", while people in fast-wave sleep say they are "dreaming".
