My WIP wouldn't let me be, wouldn't stop poking and prodding me with important thoughts to get down. Thankfully, I actually had a notebook on my nightstand, ready to go.
I wrote some furious notes in the dark (so as not to disturb hubby, of course). And then a memory of someone's comment from this post came back to me, and I worried, "What if my pen is out of ink? What if there's nothing there tomorrow morning?" I had to check, just to be sure.
