I have read a little about floaters, and some people are stating that floaters are different, and they don't appear when you close your eyes, but I don't know.
About the strange dots, The Derek got it on spot for me. It's like visual snow, the dots are everywhere for me, more in the center, eyes opened or closed. And there are A lot as well, it's disturbing and stressfull, since it started to occur only recently. And also the high pitched sounds too, yes I can hear them to a point when others claim they can't. Once there was this "Lighting Ball Lamp" in a restaurant (

Also one of the neighbors has this weird anti dog/cat thing on his loan, whenever anything approaches, it starts to ring in a quiet, but really high pitch buzz, really really bad on the ears, others say they can't hear it when walking past. It's just weird. And of course this tinnitus, it's irregular, but I always had it.
So I don't know, it started to occur not so long ago. Need to check with the doctors.
