There's a strange buzzing in my head. I'm in bed, in my bedroom. I get up, and I can localize it to something on my nightstand. It's this charging stand, on which I set my remote keyboard. Hey, I didn't know it had this stand. It seems to be designed for multiple purposes, with several interfaces that could plug in different devices, one of which is my keyboard remote, but it certainly fits awkwardly, and doesn't look specifically designed for it. I unplug the keyboard from the stand, the sound goes away, and I get back into bed.

(Migraine dream. Probably my brain trying to explain its perceptions.)
