I had a REALLY dark, scary dream last night?

Homes, i find, represent us (especially since you grew up there.) The figures can represent a number of things: fears, qualities you don't like about yourself, shadows of a bad/repressed memory. the list goes on. I need to know more.. how did you feel towards the figures? (how you feel towards EVERYTHING is SUPER significant.) The fact that they are grim reaper like is a huge pointer to death. Are you afraid of death? Black holes can represent lots of things (it really depends on how you felt towards it.) But just to give you an answer just for answering sake, they can represent nothingness/death. This could be another reference to your fear of death (if you are afraid of it) or you could be leading an empty life at the moment. I hope that helped, give me some feed back if you want to discuss it more :)
