I know a guy who keeps his beretta under his pillow when sleeping.
What if he accidently pulls the trigger when turning from one side to other?
I don't have a need to keep a loaded gun withing my proximity while asleep. But if I had an urge I would put it under the matress or in the draw by the bed. In this case it would have the quickest way in to my hands(2-3 seconds) The only concern is to not forget it's there and make sure no kids will have access to it. However, I read in the tactical shooting book that when the burglers get in to the house the first things they do is checking the bedside and jewerly drawers for the weapons. So don't leave it there unattended while gone.
