I See Shadow People

I just woke up from a four hour sleep, to a bodyless human face lying at the end of my foot facing up! the moment I attempt to get out bed, it walked off into my right in a transparent shadow then walked out the room! A week ago I woke up to my shadow walking pass my room to the other side of the house, two months ago, I woke up to two shadow kids standing on my room footsteps gazing at me! What's going on.. What is this?
