I don't know if I know the answer to that question, but it's how I feel. I walk through this world where everyone else thinks and communicates on an emotional level that I can't see, can't feel, can't understand. I see things that are real. I operate on logic and sense. And that sets me apart. I feel like I alone am real, and my world is full of ghosts live and interact with each other on a plain that's just beyond my perception. They don't even seem to be able to see me. But they are able to hurt me.
