I've seen the little stars.
I've seen the little black spots.
I know what comes next, although I admit I don't know a lot about the human body and for some reason it might be different with running.
If it's randomly showing up, it's because of sudden oxygen deprivation which is bad. When it's the result of running, it's your body being forced to the limit, and your blood cannot pump oxygen fast enough to keep up with what you need. The reason we have to run to that point is to force our bodies to improve cardio strength.
