I Woke Up This A.m. With A Dark Shadowy Spot

I woke up this a.m. with a dark shadowy spot on my right eye. Its floating around when I move my eye. this afternoon, I took a nap. when I woke up, not only was the floter still there, but now, there is like a wave of small tiny tiny floters like a wave over my eye. I ca'nt see it in the mirror, but my vision is starting to be affected.
