Bathroom
I don't like using the bathroom at night. I don't know why, but I have the strangest feeling it's haunted. My wife says I'm just being silly, but gives me an unsettling feeling. Last night, I woke up around 3 AM and noticed that the lights were on in the bathroom. I cautiously opened the door and went inside. I was helf-expecting to see some kind of hideous ghost or have some monstrous creature pounce on me, but nothing happened. The bathroom was empty. I turned off the lights, unlocked the door and went back to bed. In the morning, my wife told me she must have forgotten to turn the lights off.
