I heard a ghost story about a college dorm that caught on fire and burned to the ground. The school rebuilt it but the floors were spaced differently so the ghost would appear at the old floor’s level. So half a ghost popping up through the floor or little ghost legs popping down for the ceiling.

It seems to me that ghost location is relative to sea level. Maybe they attach to the closest neat rock in the case of a fire. Anyway, tumbling them for several weeks seems to detach the ghosts because my rock collection shows no signs of apparitions.
