Once Zhuangzi 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 Zhuangzi. Suddenly he woke up and there he was, solid and unmistakable Zhuangzi. But he didn't know if he was Zhuangzi who had dreamt he was a butterfly, or a butterfly dreaming he was Zhuangzi.
Zhuangzi, who is out of China known as Master Chuang, is a famous Chinese ancient philosopher who influenced development of Chinese Buddhism, known as Zen.
Do we dream our life, or do we live in our dreams?
