Monsters leak from the creaks that you make when your bones are old, they have no need to hide under the bed, they are the new colonists, moving in on the old ones to feed on their fears.
but you don't have to believe me, you only have to look under the bed, see, no monsters.
I stick a crucifix to the bedroom door, one on the Zimmer and several more around the room, they'll have to say their prayers to get to me.
