Went to a catholic school built on top of a grave site which might explain a few things. Every morning the entire school congregates in the great hall to say our Hail Marys and our fathers in unison. One year there was a huge plywood board sitting in the front of the room…. The wood grain looked like mother Mary holding a baby Jesus. We would also find random pools of old blood in old parts of the building… And it would be gone the next day. Also we would hear footsteps echo when we were alone only to find we were alone.
