Silence In The Library is one of my very favorite Doctor Who episodes, but it’s also one of the episodes that freaks me out the most because of this very thing.
If you want to scare me badly enough to make me run away, follow me in a zombie walk and just say “Hey, who turned out the lights?” in a creepy monotone. Works like a charm.
This design has the added benefit of being glow in the dark, so you can freak people out by turning out the lights and then following them around. Because you’re evil and you know you’ll do it.
