The freakiest unexplainable to me thing happened when I was about six or seven. I was laying in bed about to go to sleep. There was a light fixture over my bed that was held in place by a long ass huge screw. The way my bed was positioned (this house wasn't big and had no large rooms) the fixture would be positioned right around the knees of somebody laying down on the bed.
Anyways I guess I was reading or something because it was late and my light was still on when I heard something big walking down the hall. After you spend a lot of times with people you can pretty much tell who is coming just by their gait and assumed my dad would pop around the corner. The footsteps continued on and they belong to no one. They then entered my room and I was sure I was imagining it but I could quite clearly hear footsteps on the wood floor. The way I was laid out on the bed my feet were kind of separated from each other like in an A -shape. Well in between my feet
I very clearly felt somebody put their foot on the bed and watched as the mattress sink and I could feel my feet angling toward the depression caused by the invisible weight.
The light fixture started rattling, and at this time I was freaking out being a little kid, and I watched the long set screw unwind itself, fall out, and then the actual light cover for the fixture fell down a couple of seconds later in between my legs. Like somebody had unwound both items and dropped them on the bed at different times.
I ran out of the room screaming for my dad who came in there and asked why I unscrewed the light fixture and was making a racket. Looking back I don't even think I was tall enough standing on the bed to even reach the cover to get the screw out.
Everything else I've experienced I think rationally could be explained away but that freaked me out.
Nothing like that happened before or after.
I am telling you the story 100% like I remember.
