The "dark form" that was in the room with me didn't seem threatening and didn't make me feel like I was at risk at all. I've had the feeling that maybe if there is any truth to the theory that we can touch each other's dreams perhaps this "form" was a much more proficient dreamer than I, saw me stumbling around clumsily, and came by to watch. Maybe for the sport/amusement of it, maybe to make sure I didn't freak out. Who knows if any of that is really possible though hehe. Either way I don't think it was anything "menacing".
