Once, Zhuangzi dreamed he was a butterfly, but when he woke up, he wasn't sure whether he was Zhuangzi who had dreamed being a butterfly or if he was a butterfly now dreaming he was Zhuangzi.
Una vez Zhuangzi soñó que era una mariposa, pero cuando se despertó no estaba seguro de si era Zhuangzi que había soñado ser una mariposa o si era una mariposa que estaba soñando que era Zhuangzi.
