At the end of the movie Gremlins, which scared me horribly as a child, it says "Always make sure to turn on the light, before you enter a room" in a creepy way. Well, I always would flick on the light with as little of me in the room as possible and thoroughly examine before entering. To this day I do that, in the same, peeking, scared way.
