This isn't really a scary story, but I think it's worthy of posting.
This past Spring Break (2009), I slept over at my friend's house. It usually takes me forever to drift off, and even longer when I don't have my nightlight with me (I'm 16, but still afraid of the dark). I was lying awake, waiting to fall asleep, when my friend and the rest of her house had already dozed off.
Now, allow me to just quickly explain something: When someone walks into a room, you can feel their presence, right? Well, I'm usually very in tuned to people walking; their footsteps, the way they feel the sound they make, etc. I can immediately recognize the sound and feeling of a friend or relative when they've walked into a room, regardless of their shoes, the flooring, any of that. I can tell the difference, even when nervous or anxious, between footsteps and contracting/expanding pipes in a house. I know these were footsteps.
Now, that night, as I was waiting to fall asleep, I know I felt someone walking in front of my friend's bed. It was only a few steps, right at the foot of her bed. Not walking through the hallway, opening the closed door, and then into the room, but they just appeared there. I didn't see anyone, and was really too afraid to ask, but I felt someone in the room. I heard their steps. And then they somehow moved from in front of that bed, to behind me. The thing was right behind me was a wall. They walked a few steps in the wall, and then it all stopped. I didn't hear anything after that. I've slept over at her house a few times before that, never feeling or hearing this before.
I told my friend about this the next day, and I recall her saying that she thought their house was haunted, but could not recall any particular moments in which a ghost made itself known.
I plan on going to sleepover for her birthday this Friday.
