Or to put it another way, life has a new metabolism, and dreaming is a new metabolism of consciousness.
If a person's experience leads to strong emotions, it is difficult to sort them out, and dreams that express or try to solve such emotions will be repeated until the dreamer's consciousness can accept them and is less easily disturbed.
If an emotion is so strong that dreams can't be combed, it needs to be combed when you don't sleep. This is called madness.
Different from daytime, the content of dreams is usually visual and tends to be narrative rather than logical and speculative. The connotation of dreams is emotion. In the framework of fragmented dreams, everyone shows their fears and hopes.
