Oh my god. I also have mild TMJ problems, but the thing is, I've been having SEVERE dizziness for months now, ever since my wisdom teeth came in. I've been to many doctors and there isn't yet a diagnosis. I'm scheduled to get an MRI soon, but I have a theory that my teeth affected my jaw, and therefore caused me dizziness due to my jaw maybe irritating a nerve? I really don't know, it's just a theory. Anyway, with TMJ problems, I also had mild dizziness (this was a few years back before the major dizziness started)but I never did have floaters. I hope you feel better soon, good luck.
