Owen Keel - Who am I?

My name is Owen Keel, I'm 27 years old. I live alone in a NYC apartment, where I spend most of my time, well.. all of it. I don't like going outside. The doctors say I'm affected by several mental disorders, but the only one I care about is "him". The other me, I call him "evil Owen". He shows up from time to time... "emerges" (as my psychiatrist has put it) usually when things are messed up. Damn it... I had the same nightmare again last night, but for the life of me I can't remember what happened! Who am I? Where are my parents? Why is there blood on my hands again?
