I just remembered something that happened to my brother about 8 years ago or so. I thought it pretty funny:
So my bro says that this one night he was alone in the living room. We have a door entrance to the tiny as f**k hallway that leads to the bathroom, and the two bedrooms we have, and on the side of the door we have our shitty heater that has these slits so you can see through to the other side. Anyway, that door was locked that night, it was around 1 or 2AM. This was back in the day when my bro played Halo 2 online, so he was just chilling on the couch talking to his friend on the phone. My bro was, and is still a puss puss, so he had the hallway light on lol. Suddenly he says he heard movement coming from the hallway, and through the slits of the heater he saw the silhouette of something passing through a bunch of times, just making noise. My bro went and checked, and saw nothing. It could have been my sister or my dad, but they both said they don't remember getting up to head for the restroom. They probably don't remember since they would be half asleep when they would get up to piss or something.
So my brother heads back to the couch, still on the phone with his friend, when conveniently the TV happens to turn on by itself. Now this is something that actually happened with our old TV as I've seen it happen about twice, but I don't think my brother ever had it happen in front of him. Naturally he was spooked, and as the TV screen turned on, Poltergeist 2 was playing, probably on AMC.
I f**king laughed as he was clearly scared when he was telling me this the next morning.
