If there was a big black blob in my door it would likely be my dog.
It's not popular here but I always keep my bedroom gun with the magazine loaded but the chamber empty. I feel the seconds it takes to load the chamber gives my brain time to clear the fog and ensures some amount of coherency before pulling the trigger. People are known to do funny things when just coming out of sleep ... or even while partially still asleep. I don't want to shoot one of my kids while in a groggy stupor! Of course part of my thinking is based on a second floor bedroom and a large dog both of which ensure extra time that wouldn't be available if dogless and on the first floor. I love having that dog!
Nice job keeping your head and your cool!
