I hate hate hate when this happens. I was sitting, doing my homework, and watching tv, when suddenly I got dizzy. It usually means somewhere in my neck or back, the muscles have, for no reason whatsoever, suddenly gone all wonky. It happens very rarely, and with varrying intensity, but it absolutely sucks. It's not bad enough that I can't get up and move around, but it's definitely very hard, even sitting still. Dizzy and I can't do anything about it. Took an advil to loosen the muscles, but it's not working.
