Has there been any studies of people accurately hallucinating what's going on around them during sleep, by having other people talking around the sleeping subject and describing the scene? A lot of skeptical arguments against veridical OBEs focus on the person being able to construct an accurate hallucination by hearing sounds around them, during anaesthesia or cardiac arrest. So I expect this kind of veridical hallucination should be fairly common during sleep, when the brain is in a much better state than the other cases. I've never had such a thing during sleep. Has anyone here?
