Hi brooklyn,
I know that some dizziness can be caused by fibro, but like Chutz said there can be many other causes, so I would probably check with your doc if it continues.
I have an inner ear disorder that causes vertigo, and the dizziness is often triggered by my eye movements or things moving in my visual field. There is a huge connection between your eyes and ears as they relate to balance, and if your brain is getting mixed signals from them, it can really cause dizziness (and other weird sensations).
Anyhow, I don't think it sounds stupid!
