Stalked by something
The same thing happened to me
I was 21, living with my first husband, straight out of my father's abusive home, mom recently dead. I was sleeping one night and according to my husband, a dark, hooded figure appeared in the bedroom, moved toward the bed, and stood over me. Hubby was an Episcopalean and he did the only thing he knew how. "I am protected by the blood of the lamb. In the name of Jesus Christ, be gone!" He said the figure disappeared immediately and he never saw it again. I knew nothing of any of this. At the time, I was very troubled, depressed, inspiritual crisis. I've never been aware of one yet. And yes, my first thought was that it was the Grim Reaper. I've died three times now and come back every time, so I would have thought that he'd come to claim what was rightfully his.
