Well, I don't have any good ones. Mine are just little weird things, lol.
1. One time, we had this "attic" above an old metal barn, and it always freaked me out. I NEVER wanted to be in there alone. Well, I decided to just turn up my music on my computer and be up there alone. We made it into an apartment sort of thing, so it was pretty nice. Well, I felt really agitated with the loud music up, so I turned it off and just sat there. I didn't want to get up, because I felt like as soon as I would run to the door, something would get me (i was little, lol.). So I just sat there doing nothing. Well, I waited and listened, to make sure nothing was there, and I heard a man cough in one of the rooms. There wasn't anyone in there at the time, besides my little self. I heard that "man" cough and just RAN out of that place and down the stairs!
2. Well, this actually happened just last week. Well, one of my friends passed away a few months ago, and I've always had a feeling that the place was being watched by him ever since. I don't even go into certain rooms because I absolutely feel like I will see something looking at me in the mirrors. I've always had that feeling, even when he was still alive, so this leveled up the creep factor! Well, I was sitting on the couch, watching Downton Abbey, when my dog started growling at the ceiling. He was watching something, his eyes were going back and forth like something was up there scaring him. He started barking and growling at this "thing", when all the sudden, he jumped up and started CHASING IT! He was like going back and forth, growling and whining at this ceiling, while I was basically waited for something freaky to happen! He finally just stopped, I guess whatever he saw was gone, but he definitely was startled by something. CREEPY.
