Dark matter can be constituted by the baryons of mirror world, parallel hidden sector which has the same (or similar) microphysics as that of the observable world. We discuss a mechanism based on the B-L and CP violating out-of-equilibrium particle processes between ordinary and mirror sectors that could generate baryon asymmetries in both worlds, in comparable amounts, within the range , and thus naturally explain the conspiracy between the baryonic and dark matter fractions in the Universe. Particle interactions between two sectors can be also relevant for a direct detection of dark matter and in addition could induce interesting processes of the ordinary particle oscillations in their mirror partners. Cosmological implications are also discussed.
