The influence of dreams on physical and mental activity

There are two kinds of ideas that are not mysterious. One group believes that dreams are a reflection of a state or disease in the body. Ancient Chinese doctors believe that if you dream of white objects, knives and guns, it may be lung disease; Dreaming of drowning is kidney disease; Dreaming of fire roasting people is heart disease... . This view also exists in modern times, the modern saying is: when the body has a slight discomfort, people do not notice when they wake up, the dream will dream of the corresponding content. For example, a small pain in the heart area will dream of being stabbed in the heart with a knife.

Another group of ideas holds that dreams are thoughts and emotions. Caused by desire, etc. Therefore, if we have been thinking about a certain thing during the day, we will dream about it, the so-called 'day thinking, night dreaming.' If we wish to be rich, we dream of being rich. If you miss a friend, you dream about him. On the other hand, if we are afraid and worried about something, we will dream of terrible things. At the end of the last century, Freud, the great Austrian psychologist, used scientific methods to study dreams, found the essential laws of dreams, and established a scientific theory about dreams for the first time. His understanding of the meaning of dreams also falls into this category. He considered dreams to be the fanciful fulfillment of a wish. The explicit meaning of the dream is different from the implicit meaning, which is some kind of desire, and according to his theory, if a woman dreams of getting an injection, the injection is likely to represent the male genitalia, and the injection indicates that she wants the opportunity to have sex. The achievements of Freud and others made the study of dreams finally enter the palace of science. But, to this day, it is still crowded in the corner of this temple. Dream scientists are looked down upon by other scientists who are more rigorous and perhaps more stubborn. The latter asks, 'You say that dreams have meaning, but how do you prove it?' How can you tell if your interpretation of a dream is its original meaning? For example: you say that a woman dreaming of getting an injection means that she wants to have sex; And we're saying it's just because she had an injection that day, so how can we prove you're right?' ;
