At home, sick, practicing

Who are you when you wake up? Are you the same person you were the night before? What were your dreams? Were they places you went? Have you been there before? Or did they just come and go? Did the bald men in black coats come and change out your body like in that movie filmed on the meteor? All your memories are fresh and new and old as the hills.
I reckon not. I figure you are the same person, just a day older. Maybe that's difference enough.
