I've always got a kick how people will fall reverently silent and consider you blessed if you say you saw an angel or some "vision", but if you tell those same people you saw a ghost they'd tell you how full of it you were. Is there a difference? I sat in the library for 9 solid hours one day (heaven!), looking at every ghost book they had; "psychic photography", famous hauntings, the haunted; the stupid-ass "ectoplasm" photos of long-ago Mediums, badly faked portraits of spirit photography, the psychology and physiology behind those who claim demonic possession, EVP, infrared ghost photos, Near Death experiences. Maybe not. But - I know better. Hopefully I can share some of the latter here, but those debunking stories make good reading, too. Any good ghost stuff, Emaill me.
