The Crypt Keeper Knocks BACK!
This is one creepy phenomenon I know to be true, because I heard it.
In a cemetery located on Route 8 in New York State between Unadilla and Bridgewater is a crypt belonging to Eunice Welsh. If you knock or pound on the door, you will hear a rustling sound from inside, and you will have your knock returned! I have done it and I have heard it! I have tried this phenomenon twice, once alone (it scared the crap out of me) and again six months later with a girlfriend, who swears she heard a voice hiss “leave me, leave me, go!” I didn’t hear that, but I did hear the two knocks returned.
