I (rather oddly) believed that the lightswitch on my grandmother's hallway wall - which was actually the bathroom light switch - was sentient, malevolent, and biding it's time (not quite in those terms, but every kid knows what it's like to just KNOW something is evil). It's switch looked like a beak, and the screws were it's eyes. It chased me through my dreams for months, and I still can't quite figure out why I fixated on the damn thing!
