I had this dream where i saw a lake, black and white was the scene .. next to the lake there was a tree with a swing, on the swing there was a girl with her long pitch black hair in her face and as i got closer to her she looked up at me and screamed as in a terrified scream high and pitch. I awoke soon to realize that it was a real scream and tried to move.. only i couldn't yell for help or move. Im pretty sure something was holding me down. I started praying in my head and then it was gone. Has anyone had anything similar to this or might have an idea of what it was?
