Hallo CRW3
CFTraveler is probably right about in that it "was probably a dweller". Such experiences are actually relatively common.
Did you experience sleep paralysis at any point that night? If so you could have been about ready to go out of body (= OBE). But for whatever reason, either a troubled aspect of yourself manifesting as a negative thought form or an actual objective astral being, the OBE never happened. Such experiences Can be quite unnerving. But I wouldn't worry too much about it because, fortunately, such occurrences are rare and are usually, at worst, a dramatic learning experience.
