This picture, done by gerkinae is familiar to me.
When I was 8 years old, I was sleeping in my bed room with my back to the room when something punched me in the middle of my back. I woke up immediately and almost as immediately I was litterally paralyzed with fear. I remember laying there trying to turn over and see what had hit me, rigid and sweating think to myself 'just pretend like you are turning over in your sleep and they wont know.' I finally did turn over and I squinted my eyes just enough to be able to look around and there was a silhouette of a little girl next to my bed. She looked to be just about my size, but she had pigtails. It just stood there, watching me. So I just pretended to roll over and eventually fell back to sleep. I ask my mom the next day if she or my dad came in my room and hit me on the back, just trying to explain it. She said no. I asked her last year, if she remembered any of this and she did. But she said that I asked her that every day for a month.
