A detailed explanation of the dream:
Psychologist Freud believes that dreams are the satisfaction of subconscious desires, and people can effectively suppress the subconscious when they are awake, so that those desires that violate moral customs cannot do whatever they want. However, when people fall asleep or relax, some desires will avoid the inspection function of the subconscious and show themselves in various images, which is the formation of dreams.
Dreams are substitutes for human desires and the main way to release depression. In the form of a fantasy, we can experience the instinctive satisfaction of this dream. The fire of desire hidden in the subconscious can't be satisfied because of the depression of practical reasons, but the impulse and depression in the subconscious constantly struggle to form a pair of contradictions, and then form a kind of power, which is the dream.
