This happened in the '90s when I was eight years old. I was at a friend's house after school. His family had an extensive VHS collection and we were going through it trying to find a movie to watch. My friend got called upstairs by his dad who was a bit of a hardass and I thought he might have been in trouble or something.
I continued going through the VHS tapes and finally found one I wanted to watch (I think it was one of the Ernest movies). Except the tape inside didn't match the cover… It was missing the label with the movie title.
I put it in the VCR. It's a home movie. It looks like they must've set up a tripod in the doorway of the living room because you can see the whole room in a wide shot. Dad and mom are sitting on the couch, spaced apart. My fried and his sister are each in a chair opposite them. I waited 30 seconds for something to happen. Nothing does.
Then I pressed fast-forward. They're literally just sitting there, not even talking or moving. I get the feeling there's something weird and not right about this.
Suddenly I heard my friend coming downstairs. I quickly ejected the tape and put it back and never asked him about it. Not long after that he moved away. I still think about this sometimes.
