Will it ever stop haunting me?

I have a swing top wastebasket in my bathroom. Today, while I was showering, gravity did its thing and the top moved a little. I heard it and pulled the shower curtain aside in terror. Yes, even though I'm on the fourth floor, behind a locked door in the lobby, a locked door by the elevator and a locked front door, I still half-expected to see Norman Bates' "mother."

I saw Psycho at least 40 years ago, and that one scene still scares me pissless. Literally. (Cut me some slack! I was in my own shower!)
