Probably this: "In the Reign of Giants DLC, every Grave in the world will spawn a ghost during a Full Moon. "

Note that a grave does not need to have a headstone, it look like just a pile of dirt. If this is the case, you can try digging it, which may prevent a ghost from spawning there on full moons anymore.
