Rainbows?

[Pumpkins]

Sometimes when im not concentrating on anything or really bored/tired i start to see these little rainbow dots that look like they go by in a sort of "parade" way and they keep coming...and coming and coming ect untill i try to think about somthing then they go away....Can anybody explain to me what this is called or what it is? Please...Thanx

pieces of lint on your eye... if you move your eye to look at them, then they move since your eye is moving. wierd stuff i would have fun looking in the sky and following them with my eyes ... people thought i was wierd in elementary school. I would say naughty things about them under my breath then would burst out laughing. They would wonder why. I felt sorta sorry for them, since they didnt know what i said
