This type of dark matter was postulated to resolve a number of conflicts between observations and simulations on the galactic scale and smaller. Self-interacting dark matter has also been postulated as an explanation for the DAMA annual modulation signal.

Where wilt thou find a cavern dark enough
To mask thy monstrous visage?”
