My school made us go to a haunted hotel (someone was murdered on the third floor, and a lot of trippy shit happened there). Everyone was pooling in their insane experiences at our break between classes. They called this “ecology school”, not sure if any other schools do this. We were each paired with another student (same gender) to a room.
One night I woke up hearing a ton of things going on, assuming it was just the people above me. So I open the door out into the hall, and all of the sudden the noise that I am hearing stops. Down the hall I see something moving around; thinking that it was another student up like I myself, I walked closer. When it came into image with my mind, I see what it is. That being a naked man with no hair. And I mean no hair anywhere that I could see. Fully frontal, faced towards me, he is soaked in blood. Apathetic face, no smile. With me paralyzed, he turns, and opens the door to another room, and closes the door behind him, pool of blood still left in the hall.
I broke out of my paralysis, and dipped back into my own room, with the student I was paired with still asleep. I locked the door loudly. I fell asleep leaning against the door, and I woke up to an angry teacher knocking, and saying “You can’t be locking the doors”. I was out of my shock, but still had the horrific memory ingrained in my head. I never told anyone else about this until after we left, a few days later.
For reference, this was the Poland Springs Resort in Maine. There are a fair amount of reviews your can find on the internet depicting that it is apparently haunted. I found these after the trip. Now all my friends know about this, but not direct family. I will never forget that day.
