I have read and been inspired by the book
"The Afterlife of Billy Fingers".
(Not a paid advertisement. I just love the book!)

Once upon a time, I, Chuang Chou, dreamt I was a butterfly, fluttering hither and thither, to all intents and purposes a butterfly. I was conscious only of my
happiness as a butterfly, unaware that I was Chou. Soon I awaked, and there I was, veritably myself again.
Now I do not know whether I was then a man dreaming I was a butterfly, or whether I am now a butterfly, dreaming I am a man. Between a man and a butterfly there is
necessarily a distinction. The transition is called the
transformation of material things.
