A Jealous Child?

The following happened to me about a year ago. I only recently discovered the site, and have been debating on whether I wanted to publish my experience. I've been afraid to, though I'm not quite sure why. But I'm ready now, and here it is.

The night it happened, I was sleeping over at a friend's house. Her house has always made me feel a bit uneasy, and the fact that the power was out that night didn't lessen the feeling at all. When it was time for bed we tried to sleep, but it was quite hot in her room upstairs (no power, no ac) so we decided to go downstairs and sleep on the couches in her living room. It was about 3:30 in the morning.

My friend fell asleep long before I did. As I was lying awake, just staring at the ceiling, I heard someone run down the stairs. This was a bit perplexing as I had thought everyone but me was asleep. I was compiling a list of possible suspects, but then I realized there were none.

Her mother and father were asleep, and had not left the room since 10 that evening. Plus, whatever had run down the stairs sounded to be the size a young child. My friend's little sister was two, so that ruled her out. Her brother who was 7 at the time wasn't even home. And it definitely wasn't my friend as she was fast asleep across from me!

As soon as I concluded that that couldn't have been anyone in the house, I heard a loud scream. It was not something I heard with my ears, though. The scream was in my head. All of a sudden, I felt something jump on my chest and start pounding on it with what felt like little fists. It was not painful, just a really intense pressure.

I tried to yell, but I couldn't. I could barely even move. I gathered up all my strength and managed to mutter, "Who are you? What are you? What do you want from me?"

Everything stopped in an instant.

As you can probably imagine, I didn't sleep at all that night. The following morning I left without saying much to my friend. When I finally did tell her about what happened, I found out something quite interesting.

Apparently, she used to see a little boy in white sitting outside her window. Whatever ran down the stairs and jumped on my chest sounded and felt like a little kid.

Here's one of my theories as to who this ghost was, and why it targeted me. I believe it may have been that the spirit of a child saw my friend as HIS friend, and wanted me gone because he was jealous. Of course, maybe it was something else entirely. I'd love to hear what you think.
