What are you?

What I am getting at is, what do you believe yourself to be? Dualism is a belief that you are a spirit separate from your body and that you use your brain to control your body; but that you are quite separate from that body and that brain. Do you believe in dualism, or do you believe in physicalism, a philosophy that says you are your brain and your body’s nervous system; and that the sense we all have of being a separate little homunculus inside our heads is an illusion? What is your best guess about dualism versus physicalism.
