Sleeping with guns is quite uncomfortable. Sleeping near them seems to be a little easier.
There have been a story or two on DC.com where someone sleepwalks or moves a firearm during the night. If that is the case, please put some sort of lock between you and your firearms.
Honestly, I believe all firearms should be under lock and key or on your person at all times. Anything in-between invites trouble. It only takes a few seconds to open a pistol safe. If you don't have a few seconds to spare, you need to improve your early warning signs.
