Dark Matter seen by its gravitational effects. There is no
fundamental theory of particles that describes Dark Matter, all the
possible normal matter candidates have been eliminated.
Antimatter has been seen, and combined states such as anti-hydrogen
and positronium have been investigated.

"collide" even with other Dark Matter.

Yes.
