Note to self: Obtain a nightstand.
That made me chuckle. I have a bookshelf, myself.
At any rate, revolver + spare loaders, flashlight (and a spare), cell phone. That's the baseline minimum.
I like the idea of the aid kit (though I'll be putting that in the closet with the bug-out bag, a separate deal).
The phone, as mentioned by many others is a darn good idea. Any high-quality defensive class that covers bump in the night can explain why better than I.
I also have a tasty knife or two, but that's sort of a vanity. On the other hand, the emerson clipped to the side of the bed may be easier to reach in a worst case scenario where someone is already on top of me; at that point I'd personally rather have mr. sharpie at hand than fluffy the pet revolver... other opinions may differ.
For whatever it's worth, I also have the clothes that I wore that day previous right next to me; I can throw on the pants, shoes and t-shirt and, in addition to being clothed, I'll have my wallet, belt, CWP, and a spare Emerson in the bargain. I always swap stuff out of pockets the following morning into whatever I'm wearing next.
I need to invest in a good quality flashlight.
Again, FWEIW, I just picked up another one; so far, so good with this tool:
