Just wanted to chime in here with a semi-related experience. Don't remember my dreams very often, but had one within a year ago where I was in my girlfriends house, walking through the 3 rooms on the bottom floor except in the middle room I saw (where the wall should have been) the grim reaper peering into the window of a house. Thinking oh shit, I went into the bedroom and laid down, and as I did the reaper peaked into the room and stared directly into me. Creepy! This one had a skeletal face instead of a void, however.
