Chaos Theory

Once upon a time I dreamed I was a butterfly, fluttering higher and higher, to all intentions and purposes of a butterfly. I was conscious only of following my fancies as a butterfly, and was unconscious of my individuality as a girl. Suddenly I woke, and there I lay, myself again.

Now I don't know whether I was then a girl dreaming I was a butterfly, or whether I am now a butterfly dreaming I am a girl.
