Of course I believe in Ghosts. It's those little guys that kick ass in StarCraft. Not to mention, the new Nova chick.

But do I seriously believe, naw. I think it's our own brain and tension that "makes" them real. But then again, how do you really define a ghost. If someone haunts you in your mind, wouldn't that still be a ghost. So in conclusion, physical ghosts, no, "mind" ghosts, yes. (sorry, I couldn't of a better name)
