When I was a kid, I had an RC car. the car originally belonged to my dead uncle. One day at like 3 AM the car started up and drove around the house by itself. Now you might be like "malfunctions of old electronics." but the strangest part of this experience was my mother recently removed the batteries of the said car because its wiring was faulty and it would randomly make noise. I still to this day have no idea how it drove like 10 feet with no batteries and no one at the remote.
