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.
