" remember waking up from a dream and not being able to move and through the corner of my eyes seeing a man in black standing over me, and by the time I got through praying and being able to move it was gone (10-15 secs)"
No lie. The exact thing happen to me a couple of years ago. I remember not being able to move and closing my eyes, then when I reopened them, nothing there. I still am very freaked out about it.
