I would actually say that is a great reason to keep the gun as close and accessible as possible. What would you do if she was an actual intruder, ask her to wait while you opened your safe? This is also why I do not turn off all the lights, because otherwise you can't see shit.
I keep mine locked up in the Mini Vault right by my bed (as I said earlier)... my head doesn't even have to leave the pillow... 2.5 seconds to have the Glock 19 in my hand...
More importantly... the 19 has a Streamlight TLR-1 on it just for the purpose you mentioned above. So I can light up the room immediately to ID the person entering. 80 lumens is plenty of light to 1) illuminate the room for ID... 2) to blind the person coming in to give me an extra second or two.
I guess a flashlight stored along with the gun in the safe is fine for these purposes too... but that's 2 things to get out of the safe instead of one.
