One day Zhuang Zhou dreamed he was a butterfly. Flitting here and flitting there, just fluttering around doing as he pleased, he was so happy he didn’t even know he was Zhuang Zhou. But then, suddenly awakening, even though he was himself again . . . he didn’t know whether it was he who had dreamed he was a butterfly or whether it was a butterfly who had dreamed it was Zhuang Zhou. But there must be a distinction between the two. This is called the transformation of things.
