i have and still do on some occasions see small lights moving around. it is difficult to express how these look like. it is usually when i am reading a book or when i look into the sky. the closest thing that describes it is what bacteria would look like under a microscope. except this is the smallest whitest lights. beautiful and random.. this really only started last year. i was sitting on the pavement outside of my home and saw these lights all over the path. then it progressed onto books. i assumed it was something to do with my eyes. still not sure..
