Warning: the following was written way the fuck past my bedtime and I'm totally exhausted. None of this is really proofread, and will likely come off as a rambling mess.
I never really believed in ghosts. That said, I absolutely have a ghost in my house. It's a five bedroom home, and for three years, I was the only one living here. Every now and again, maybe three times a week, I'll hear footsteps, very clearly, walking around the upstairs hallway (upstairs being the first floor, my workshop, bedroom, and living room are in the basement). Whatever that thing is, it's wearing shoes, but more likely boots. The cocksucker is loud and unmistakable. My keys and usual pocket contents go missing all the time, and I make a point of putting them in the same place every time I empty my pockets. Sometimes I come upstairs to the kitchen, and every single one of my cupboards are open. Once, I saw one of the cupboard doors swing open open, heard the magnetic latch release, watched the door move back and forth in a way that no amount of wind could emulate, and then it slammed shut. I can't tell you how many times I've carried a loaded gun upstairs to what I thought was a home invasion, only to find that my dishes were knocked to the floor, with no sign of entry. I've checked every crawlspace, nook, cranny, and attic, and I don't even have any evidence that some homeless cunt is stowing away somewhere.
Even more creepy, although, I'm not sure if it's related, I was digging an allotment in my backyard for some plants I had vegetating in my greenhouse, when I hit some chickenwire about a foot and a half deep into the ground. I pull that out, and under it was a rose, a set of grill tongs, two pieces to a grill, and then a huge, thick, steel grate, like you'd see in a sewer drain or culvert. I didn't really try to dig that up, because I'd probably have needed to rent equipment to actually get it out of the ground, and for all I know, it could have been something for the utilities, but that rose had me spooked. Sounds like some real creepypasta shit, but hand-to-gosh, I swear it all happened.
I should probably install a security camera.
Bonus: My wife tells me that she had some real demon-level experiences in her childhood that were corroborated by her parents and extended family. She told me about the creature in her closet that would talk to her for weeks leading up to her grandmother's death, telling her to do things, and the one that really stuck out to me was that she was told never to look into that closet by the creature itself. Her grandmother was murdered in the room next to the one she was sleeping in, by her grandmother's boyfriend. Police reports say that she was beaten to death, but to such an extent that she was completely gored, and the impacts from the beatings were so intense that no human being of normal strength could have possibly dealt that kind of damage. Her family told me that the guy was in a weird, trance-like state, speaking in a voice that wasn't his. The family escaped the house and got into their car, with the guy chasing after them. Apparently, he reached his hand into the car door, and her mother slammed it shut, with absolutely no reaction from him, just a cold stare. Long story short, they drive off, and a few months later, the house burns down. It was in the local news for months, and the story even made its way into a book. I'm omitting a lot of details so as not to powerlevel, but I assure you that this shit is a million times creepier in detail. It's super fascinating, and every once in a while, I get a little more info out of her family regarding the incident.
