ive got something which i believe is the same thing, if i look at the sky and focus it looks like all of these sperm looking things, and they are moving fast and all over the place, and the beginning of them looks like light. I also have a floater i dont know if anyone else has anything like this, but it is a black dot that i see all the time, when im reading or bored i notice it and it floats over everything, its weird but i get use to it.
