The first time I noticed it was when I was 4 or 5. I didn't exactly know what they were, but I noticed that I saw some green dots in my vision when there shouldn't be anything like that.
I was intrigued, but a little scared as well.
I asked Mom what they were. She told me they were called 'floaters', kind of like specks in your eyes which become more noticeable when you are looking at light colored background, like a white wall or blue sky. These floaters seemed to be floating around in the air, hence the name floaters, but in fact they were in your eyes. Apparently.
But these floaters started to bother me.
I noticed that I didn't only see them when my eyes were open and looking at a light-colored surface as I was explained to. I saw them inside my eyes at night when I lay down to sleep. And they didn't really 'float'. They were more like blipping green dots.
