Name a thing or event from your childhood that scared you?

I was about twelve. Waiting along a country road for the 10 p.m. bus home. Opposite a ruined house that was supposed to be haunted. I saw a dim light like a candle moving from room to room upstairs where the floor was supposed to have collapsed. The light went out but I thought I saw a figure standing near me. Telling myself not to be silly I nevertheless ran out into the road when I thought the bus wasn't going to stop. An irate driver : "We're not supposed to stop along the road when it's dark, lad". Realising I'd been scared : "Was that guy standing beside you annoying you? ".
Yeah. Still scary.
