Please read where the "dark matter" term came from. It's not a faerie dust
that facilitates magic use. It's just a hypothetical matter in the universe
that we can't observe, because for some yet-unknown reason it doesn't emit
light. There's no reason it can't be just regular matter.
Neutrinos don't interect with EM either, so just being "dark" is not outside of well established physics. The only thing strange about "dark matter" is not that it is dark (eg, not interacting with the electromagnetic force), but that none of the dark particles we already know about can explain the effects that we attribute to dark matter.
