Replying to Personal Ghost stories/Encounters

Thizzle.'s thread gave me the idea. But does anyone else have some crazy stories they wanna share? I love reading them and i wanna hear yours.
Ill start: The only one ive ever had was in like 8th grade i think my friends were talking about going to a place called the 7 gates of hell (its some pretty crazy shit, google it.) They arnt to far from where I live here in Pa. I found the 7 gates intriguing so i started researching it my self. It was a sunday and the only other person home was my sister and she was napping on the couch. So I was sitting at the computer reading about these gates when my key board just slid across my desk really fast. It was probably one of the scariest moments of my life. So i went and just sat next to my sister but i didnt want to wake her up. So i sat there and watched a Viking's game... scared shitless.

I did search bar and i couldnt find anything so if this is a repost im sorry :/
