this is true and we both heard it,absolutely terrifying and it has transformed both of us forever and...of course... no one believes us!...one winter night he and i were taking the short cut between his house and mine which is a road that runs through the middle of this cemetary...as we were walking along,all of a sudden this very loud sound of evil cackling laughter "burst" right in front of us!it escalated into demonic growls and shreiks!and trailed off into into inhuman moaning as we were running away,this sound came out of nowhere and was very close to us,it wasnt human at all, it wasnt any animal either,not even close,we couldnt sleep normally for weeks afterwards,if i only had a recording of it! because listening to it would "prove their existence" and scare the hell out of anyone!
