Sorry, I meant bend. Lol
Ok, I'm sat here now, and if I bend my head over my shoulder as far as it can go, to look backwards, when I then turn my head back I can now see them. They're like little bright things floating in the sky. If I look up (just my eyes, not moving my head) I see more of them, and likewise if I move my eyes to the left or right. They stay there, just moving around, and then fade out after about 30 seconds.
30 years old, have had it for a good few years. It's not something that causes any kind of problem, I just had it this morning in the shower and it seemed to last for a long time, so thought I'd ask.
Any ideas?
