Difference:
A dream Conan-Conan satrap biography, write a dream of spring rain and drunkenness, and serve as Conan satrap for 20 years. When he woke up, he realized that Dahuanguo was an ant nest under the big locust tree in the south of the house. Therefore, later generations used Conan's dream to imply that the prosperity of the world was just an empty dream. Now it is often compared to an empty happiness.
Huang Liang's dream and Conan's dream have the same meaning, but there are fundamental differences. The former is that he failed in the exam, and his mind (supplemented by external factors "Taoism") is subjective; The latter's drunken dream is due to. Shallow consciousness cannot be controlled by cerebral cortex consciousness. So this can be said to be passive.
These two dreams are completely different from Zhuangzi's Zhuang Zhoumeng Butterfly.
Zhuang Zhoumeng Butterfly:
Meaning: A metaphor for a confusing scene or a memory of the past. Zhuang Zhoumeng butterfly, I don't know if Zhuang Zhoumeng turned into a butterfly or if the butterfly dreamed of seeing Zhuang Zhoumeng.
Zhuangzi dreamed that he became a butterfly one day. When he woke up, he found that he was still Zhuangzi, so he didn't know whether he dreamed of a butterfly in Zhuangzi or a butterfly in Zhuangzi. Here, Zhuangzi raised a philosophical question-how people know the truth. If dreams are real enough, people have no ability to know that they are dreaming.
It is Zhuang Zhou's great fortune that become a butterfly is a butterfly, moving from a noisy life to a happy life. The butterfly dream is Zhuang Zhou, and it is probably the sorrow of the butterfly to step into the noisy life from the carefree realm. But Zhuang Zhoumeng's butterfly is his yearning realm and his yearning choice. Not everyone longs for a happy life. Butterflies dream of Zhuang Zhou, which is their choice. We can't generalize
This theory is widely used in philosophy. Zhuang Zhou's dream butterfly is a philosophical argument put forward by Zhuangzi, who believes that it is impossible for people to distinguish between reality and illusion.
