Reminds me of the story of Chuang Tzu.
He had a dream that he was a butterfly, and had always been one and knew nothing except being a butterfly, and then he woke up and found he was Chuang Tzu. But he was not sure whether he was Chuang Tzu dreaming about being a butterfly or a butterfly dreaming about being Chuang Tzu
