I've never slept with them because I fear for my life or for defense, but I have just to try to scare my parents in the following morning.
I slept with my blank gun (Beretta 92fs) for about 2 weeks before I sold it to a friend. I shot it all the time in my house. Good lulz for my parents haha
Never slept with anything else really, but rarely I might have a flashlight under my pillow for anything that comes up
