Nope. Never seen on. Wouldn't want to see one. Denial is a wonderful place. I go there often! I have read though, (because I'm not a closed-minded person just a chicken shit), that they won't show themselves if you really don't want them to. True fear will keep them at bay. If I did see one, I wouldn't see it. I would simply deny I saw anything. The thought of ghosts creeps me out!

Sorry, ghosty! No offence!
