Butterfly or Chuang Tzu or ... ?

'Chuang Tzu' is an ancient enlightened master from China. He belongs to the chain of Lao Tzu.

People had always seen him laughing. No one had ever seen him in grief. But one day he got up in the morning and sat in grief silently. His friends and the villagers came and asked him that we have never seen you in grief and pain. You were always cheerful. Whatever might be the situation but we always saw you smiling. Why are you dejected today?
Chuang Tzu said to the people, 'Today I am in a puzzle. Last night I saw a dream in which I became a butterfly. I flew all over the garden and the flowers and collected the nectar.' The people said, 'What is the problem in that. You can become anything in a dream.' Chuang Tzu said, 'Its all right. But when I got up in the morning, one question has started disturbing me. If Chuang Tzu can become butterfly in a dream. It is also possible for a butterfly to sleep and see a dream that it has become Chuang Tzu. And now I am unable to decide who am I? Chuang Tzu or butterfly?' Now the people got puzzled, they had never thought it in this manner.

It becomes very difficult to decide what is true. Not only in a dream but also in real life. Whatever is seen seems to be true only because the other people support it. But If all the people are in the same dream then!!!
