Ghosts can't possibly exist. How can a consciousness exist and move around without matter? My mind can't even begin to process this stuff. I'd have to go back and fundamentally disagree, with what I think 'humans' are, and consciousness, and physical mass. My head hurts.

Edit: Also, if people see somebody standing at the top of their stairs in the darkness, and they go "Whup, ghost", then I can only say they are ignorant. Because like somebody else said, the mind sees certain objects as human because we're hardwired to process things like that. Plus the fact that you could be dreaming, I've been doing a lot of research on sleep and dreaming lately because I'm trying to learn to lucid dream, and some of this stuff's really interesting. Like 'False awakenings', those are annoying.

I'm getting off topic here, but the point is, ghosts don't exist, and aliens probably don't float over fields in big dinner plates. End.
