Here's a few.
They don't sound impressive, explosive or awesome, but i guaran-fucking-tee you they were terrifying at the time.
One time I was sitting in my living room playing some video game. i had a curtain next to me. It moved. Not a little twitch but it shuffled aside like some mother fucker swung his hand and pushed it all aside. I froze, absolutely fucking terrified, wondering if the windows were open and i was about to get my ass murdered. Finally i found my balls and moved the curtain aside. Nothing. No AC or anything else was on to explain this, and i don't have pets, critters, or pests. Weird as fuck but whatever I thought.
Another time.
So once I had this chubby girl over for banging. So after bang we're watching some TV and she says she has to go to the bathroom. OK i don't have TP in my guest bathroom so use my master. OK she says. I stay and watch TV, she goes and does whatever.
a couple minutes later my bedroom door SLAMS. No air conditioning or any shit was on, the god damn door was wide open. I had my back to the door and was like ok wtf is this bitch slammin my shit for? So she opens the door with a terrified expression and said she was walking out the room when the door just slammed.
So i make up some shit about pressure changes and maybe the AC was on and she pointed out the obvious idiotic flaws and said 'that was really weird' being an atheist herself iirc she clearly didn't want to make much of it. but it was fuckin weird.
another time i was sitting on my bed watching netflix solo while texting some chicks. My bedroom door was open, lights were off. My bedroom door was a standard wooden door, you can't nudge it more than a couple inches. So i'm sitting watching TV and the god damn thing moves a foot. As I look at it it keeps moving and all I want to do is shit myself.
Finally it stops. After saying something sarcastic to mr. ghost I grab my rifle and investigate every room. Of course it's only me, but i know what I saw, shit opened up about 2 fucking feet, and it's not a light door either. Something fucking moved it.
I had an otherwise completely normal friend who said he would see weird shit sometimes growing up and told me to put salt on my door. I rented the place out instead and moved my ass out. One of the new tenants was a college girl who claimed i had pests because she would hear shit at night. I had the place sprayed just to shut her up, but the guy said he inspected it and the inside and saw nothing.
So yeah. Fuck that place. Like I said, nobody believes this shit is real till it happens to them. I sure as shit didn't. But I can't deny what I saw.
Anyway, a parallel dimension would make me feel better than an actual presence, so im gonna go with that.
