"Once upon a time, I dreamt that I was someone else, somewhere else, to all intents and purposes another fraction of myself. I was conscious only of my happiness as that fraction of myself, unaware that I was my original self. Soon I awakened, and there I was, veritably myself again. Now I do not know whether I was then dreaming I was a fraction of myself, or whether I am now that fraction, dreaming I am my original self."
