One time I moved into a new apartment, it was this big loft in a converted warehouse. I had this automatic soap dispenser that went nuts on me and made this really scary sound, I thought the place was haunted!
Haha yeah it was pretty funny once I realized what the spooky sound coming from the kitchen was.
I turned off the TV and my phone and tried to trace the sound to its source. I feel ridiculous about it now in hindsight!
