I fainted recently during acupuncture but definitely had a dream. The combination of the pain..then fear set me off and my body just reacted. Cold sweats, nausea and dizziness and then my hearing faded and I fainted. I definitely didn't fall asleep. I don't know how long I was out for but how is this even possible? I can't remember the dream but do remember it was a pleasant one with quite a few people in it. I was not conscious at all of my surroundings while I was out.
