“Life is like a dream” is a Chinese saying, an old saying that is constantly repeated by people. Tracing back to its origin, it comes from the end of “Zhuangzi·Equality of Things”.
“Zhuangzi·Qiwulun” contains: “In the past, Zhuang Zhou’s dream was a butterfly, and it was a butterfly. It was a self-reported aspiration! I don’t know Zhou Ye. Suddenly, it is a butterfly. I don’t know Zhou’s dream is a butterfly and a butterfly? The dream of a butterfly is Zhou Yu? Zhou and Hu Die must be divided. This is called materialization.”
It is said that one day, Zhuang Zhou dreamed that he became a butterfly. At that time, it was a dancing butterfly, very happy and leisurely, not knowing that he was Zhuang Zhou. After waking up from the dream, it was Zhuang Zhou who was lying on the bed. He thought over and over again, but he was still not sure: did Zhuang Zhou dream that he turned into a butterfly, or did the butterfly dream that he turned into Zhuang Zhou?
Which of the two is the real existence?
The life experience we think is real during the day and what you experience in your dreams at night cannot be mutually denied, and have exactly the same logical value.
