I don't spend very much time around graveyards. Usually I say a prayer for those who have gone before me so they may rest in peace, putting myself in the hands of Christ the Redeemer; and for those hard-to-manage ghosts, there are these prayers if I happen to have a priest handy or variations thereof. http://forums.ledzeppelin.com/uploads/emoticons/default_blink.png' alt=':blink:'> Otherwise, in the absence of an actual priest, a plain Our Father will do.
Personally, I kind of prefer the Bigfoot stories and films; but just the other night I was watching one of those paranormal investigator shows, and wouldn't you just know it, they were solving the mystery of a demon-infested house, and conveniently by the show's end that house was finally free of the ghosts that had seemingly haunted the inhabitants. Seems one of the ghosts had the hots for the young woman who lived there, and you know how that story goes.
