Obviously we would need a psychologist that specializes in sleep studies to accurately answer this question, and that is not my specialty, also, most psychologists are lefties to the crust so we may never find a good answer, but I would think a simple hand, finger twitch at the right moment could/would give a person a rude awakening. If the person was indeed friendly with the opposite sex then they could be in for some serious surgery followed by a quick divorce. I am sure that only a certified idiot would sleep with a loaded firearm, especially a revolver or auto in condition one. Besides my wife might not like the oil on her pillow cases as well as burned powder residue. What did I win? I do so hope it goes bang! Gimme, gimme, gimme!
