The following is an introduction about dreaming:
The ancients believed that there was always a reason for dreaming. Wang Fu once said: "If people dream strangely, they will gain more and accomplish nothing less." He thinks there is always a reason for dreaming. There are psychological and physiological reasons for dreaming, but even in these two aspects, human beings still can't explain the formation mechanism of dreams.
The events and scenes formed in dreams come from people's existing cognition and memory, including sight, hearing, smell, taste, touch and feeling. All these elements that appear in people's dreams are based on memory.
Hao Bin, a famous clinical psychologist in China, believes that the content of dreams is actually produced by the functions of perception, memory and storage of human nervous system, and it contains people's subconscious desires and emotions. If we can understand in the company of professional workers, it will help people explore their inner world.
