"People have been saying that Darkrai has potential to be the counterpart w/ Arceus, but it's actually a countepart w/ Cresselia. Cresselia represents good dreams & Darkrai bad dreams."
I think that's quite obvious in D/P. After you defeat the Elite4 and talk to the family with the kid who has nightmares, the kid says "There's a Pokemon, DARK.. DARK", and you get the Lunar Wing to cure his nightmare by awakening/releasing Cresselia. An interesting plot idea in my opinion, too bad it doesn't carry on.
