You know when you sneeze you see those floating dot's everywhere.But after a couple second's they just vanish.But for me everytime i try to get some sleep they appear after like 10 minute's or so. And they dont move they just fade in and out. I think there very annoying somtime's you feel as if you're looking at the night sky.And the more tired or sleepy you are the worst they get.And i find if you really think hard about somthing the brighter they get. I heard it's the begining of HI's but cant be it too early for that im only be in bed for a 10 minute's when they start. Any one else have this happening to them during the night?And what are those dam dot's
