Zhuangzi was ironic before Bodhiretard

昔者莊周夢為胡蝶，栩栩然胡蝶也，自喻適志與！不知周也。俄然覺，則籧籧然周也。不知周之夢為胡蝶與，胡蝶之夢為周與﹖周與胡蝶，則必有分矣。此之謂物化。

From Burton Watson's Complete Works Of Chuang Tzu:

Once Chuang Chou dreamt he was a butterfly, a butterfly flitting and fluttering around, happy with himself and doing as he pleased. He didn't know he was Chuang Chou. Suddenly he woke up and there he was, solid and unmistakable Chuang Chou. But he didn't know if he was Chuang Chou who had dreamt he was a butterfly, or a butterfly dreaming he was Chuang Chou. Between Chuang Chou and a butterfly there must be some distinction! This is called the Transformation of Things.
