I will start off by saying I've had many strange and creepy experiences with the supernatural but this tops it.
A little backstory, the house I lived in was haunted and also had multiple deaths, but the spirits in no way were harmful.
So in March of this year, I was having a few drinks with my roommates, having a great time. I ran to the bathroom and decided to look into my room. A couple weeks prior to this I noticed a tall dark shadow figure standing in the corner. So I go into my room, and what happens next I have no recollection but my roommates confirmed everything.
I ran out of my room screaming that the shadow was back just hanging out in my closet. Afterwards I bolt out of the house and flagged down a car and told the driver I couldn't be in the house anymore and that something was after me. After this I took off running to the back of the house, my roommate finally came out to find me slouched over with my head dangling, so he put his hand on my shoulder to get my outdoor motion light to turn on. He turned around for maybe 5 seconds and I just disappeared into thin air, I quite literally poofed. He said I didn't run or walk, I was disappeared without a trace for 15 minutes.
My roommate and his sister said they heard me yelling and cussing at something all around the house but yet they never did see me anywhere. I finally managed to come to and got violently shoved to the ground. No memory of anything, I have no idea where I poofed to or what I was trying to fight off, but I do know a thing that lurked around my house was about 8 foot tall, red eyes, horns and hooves.
Fast forward to a week later, I was waking up with bruises and scratches and no idea where they came from. Well that night, I was having a drink when I blacked out (not from the drink, mind you), and when I came back to, I saw blood all over my house. I had been scratched on my nose, but it wasn't a scratch, it was a claw mark. I don't know how it got there or what caused it, I have such a gap in memory of both of these incidents. Very terrifying experience and I'm working on looking into where I disappeared to and why.
