Then look at the reality. You're half asleep. They are fully awake. Your gun is safely stored in a safe (or you are a criminal yourself and why should I care then - you're a greater risk to your children if you don't lock it up than criminals will ever be). Their guns are loaded, your bullets are stored safely in a separate location (ditto - that's the law). 
Even if you manage to lock and load, now they STILL have the advantage. You are one person in the dark, their eyes are already adjusted. You have to aim carefully less you end up shooting your own family instead of your target (a la what Oscar Pistorius claims happened) - THEY can just fire at anything that moves.
You are scared. They have done this a thousand times. 

Trained FBI agents only hit their targets in gun-fights 1 out of 10 bullets. Criminals hit people with 6 out of 10 and mass shooters 9 out of 10. It makes a HUGE difference when you don't care WHO you hit. 

Reality: you'd be better off with a baseball bat.
