Dreaming can also digest human negative emotions. Some scientists have shown that when people are dreaming, their brains are very active, and they can digest these negative emotions and reach a balance point with reality in their dreams.
There is also science that shows that dreams are a repressed export, that is, people's unsatisfied roles in reality can be realized in dreams, which is what we call dreams come true.
Dreams can mobilize our ability to escape and adapt, and can mobilize the initiative of our senses. This can simulate the way human beings save themselves in trouble. In fact, it is a manifestation of human survival instinct.
