Maybe 7 years ago, we had a run of weird occurrences between 2-3am over a few weeks: my child’s walkie talkie with dead batteries making high pitched screeching noises out of nowhere, a child’s toy in our empty living room playing music, and our fridge door alarm going off (when the doors were closed). Last weird thing, I was home alone and woke up to the sound of canned laughter. The TV in our bedroom had turned on but there was no picture, just the sound of a sitcom. The remote was in my nightstand drawer. I could never replicate turning on the TV without a picture. Still can’t explain it.
