Once upon a time, I dreamt I was an owl, fluttering hither and thither, to all intents and purposes a owl. I was conscious only of my happiness as a owl, unaware that I was myself. Soon I awaked, and there I was, veritably myself again. Now I do not know whether I was then an enby dreaming I was a owl, or whether I am now a owl, dreaming I am an enby.
