Who knows, perhaps Grimm is the physical manifestation of Man's negative and destructive emotions that have somehow infused itself with Dust? Dust is still an vastly mysterious energy, it's origins and other properties unknown, and it's probably been around longer then Humankind has, before they used it as an weapon to fight the Grimm.

Plus the Grimm have been around as long as Humanity has, which could support this theory.
