===Dream argument===
While people dream, they sometimes do not realise they are dreaming. This has lead philosophers to wonder whether one could be dreaming at the moment (or at least that one can't be certain that he or she is not dreaming). In the West, first formally introduced by Descartes in Meditations on First Philosophy. the dream argument has become one of the most popular skeptical hypotheses. In the East, this type of argument is well known as "Zhuangzi dreamed he was a butterfly" (莊周夢蝶 Zhuāng Zhōu mèng dié) introduced by Zhuangzi. It relates that one night Zhuangzi dreamed that he was a carefree butterfly flying happily. After he woke up, he wondered how he could determine whether he was Zhuangzi who had just finished dreaming he was a butterfly, or a butterfly who had just started dreaming he was Zhuangzi.
