Freud said in "The Analysis of Dreams": Dreams are meaningful. Dreams are a true dialogue with one's own heart, a process of learning from oneself, and another life that is closely related to oneself.
Intention: In the past, Zhuang Zhou dreamed of a butterfly, which was like a lifelike butterfly. I don't know Zhou Ye. Suddenly I feel like I'm in a state of confusion. I don't know that Zhou's dream is Hu Dieyu, and Hu Die's dream is Zhou Yu? Zhou and Hu Die must be different. This is called materialization.
