My house is probably haunted. I have a LOT of stories for it! It's only around 50-55 years old, but we have some old furniture in my room (which is what we presume haunted) that belonged to my great-grandma. Only a few months ago, my friend slept over and, around 1:30am, I had fallen asleep. She couldn't fall asleep, so she decided to read. When she did, she heard someone running down the hallway and into the bathroom, then slamming the door. She got up to see who it was, thinking it was probably my brother or sister. She knocked on the door and there was no answer, and then, when she opened it, no one was in there... I know this is true, because she is my best friend and it's not like her to lie like this. Plus, I've had a few more experiences myself...
One day, I was home alone. My mom had gone out to pick up my brother and sister from school. I was on the computer, and all of a sudden, I heard someone running around upstairs. I was really freaked out, because my dog was locked in her crate in the kitchen, and the cat was outside. Besides, she's too small to make a noise like that.
Another time, I was in my room alone and the TV was on, but I was sitting in front of the TV doing my homework. All of a sudden, the TV turned off! I thought maybe at first it was broken, but it was brand new and we hadn't kicked it or anything like that.
Finally, one more time, I was in my room upstairs, and it felt like someone was sitting on the end of the bed. I sat up, thinking it was my dog or something, and no one was there. I turned on the light and no one was in the room, hiding or anything.
So those are my stories. I'm sure I have more, just can't remember them. I'm not making them up, but I'm sure there's some skeptic out there who can explain. I certainly hope not, because there's nothing like a good ghost story!
