If my house was the setting for some super creepy horror thriller movie, it would be centered around the spooky noise that keeps erupting from my bath tub drain. It's a noise that occurs at seemingly random intervals. A scratching, gurgling, strangely metallic drain noise. Clearly, there is some horror trying to get my attention to go over there and stick my head over the drain or poke my finger into the hole that would eventually lead to my gruesome and graphic demise.
