Alfred Hitchcock said that the scene in Psycho worked so well because the shower is the place where we’re devoid of almost all our senses.
We can’t see. We can’t hear. Even that feeling you get that allows you to tell that someone is in the room – gone. Taking that into consideration, it’s amazing that everyone isn’t killing everyone in the showers (and that Antoine Dodson doesn’t have a song about it). Serial killers will probably figure this out soon and just wait until you’re in your shower to kill you. Your only chance for survival is to make them believe that you are already dead. This shower curtain and mat will go a long way towards that goal. Thanks, ThinkGeek.
