Chuang Tzu was a philosopher in ancient China, who, one night went to sleep and dreamt that he was a butterfly.
He dreamed that he was flying around from flower to flower and while he was dreaming he felt free, blown about by the breeze.
He was quite sure that he was a butterfly at that time. But when he woke up he realised that he had just been dreaming, and that he was really Chuang Tzu dreaming he was a butterfly.
But then Chuang Tzu asked himself the following question:
"Was I, Chuang Tzu dreaming I was a butterfly? Or am I now really a butterfly dreaming that I am Chuang Tzu?"
