Answer:
I turn everything around, but I cannot move. When you see me, you see you! What am I?
Never ahead, ever behind, yet flying swiftly past, for a child, I last forever, for adults, I'm gone too fast.
I stink up your breath and fights evil vampires
No legs have I to dance, no lungs have I to breathe. No life have I to live or die, and yet I do all three. What am I?
I move without wings Between silken string I leave as you find My substance behind.
No matter how little or how much you use me, you change me every month.
