i used to have a bed with drawers underneath the mattress that went all the way to the floor (so there was no underneath). Anyway, there was a big narrow "drawer" that went all the way to the back that was empty, and i used to believe that if aliens or monsters came, i could hide in there and they would never be able to find me.
