The Wikipedia page on MACHOs (MAssive Compact Halo Objects) gives a good summary of the research into non-luminous ordinary matter as a dark matter candidate. It just about universally demonstrates that such objects can only account for a small fraction of all dark matter.

I still think dark matter's just non-luminous matter without a convenient light source to reflect.

We've just about ruled out the idea that dark matter is just non-luminous "ordinary" matter.
