The Dream Realm is a location exclusive to Pokémon Insurgence that is accessed from within the player's own subconscious. At times it is also referred to as the Nightmare Realm as Darkrai is responsible for managing everything within the Dream Realm. Though it is obviously never referred to as such by any characters within the game, it effectively makes up a smaller third region in Pokémon Insurgence.
The Dream Realm has no known history as it likely was created shortly after Darkrai itself came into existence. Additionally, because the Dream Realm is actually a collection of the subconsciousness and dreams of all people, it can be said to be ever changing based on the people involved. It seems that altering a person's memories also changes or destroys parts of their Dream Realm, as Persephone reveals this to be the main reason why she insisted upon wiping the player's memories in the beginning of the game rather than getting rid of them outright.
The area that connects the Dream Realms of many people is referred to as the Nightmare Badlands and is also said to be Darkrai's domain. Though the player ultimately does find him or herself venturing into the Nightmare Badlands in order to call upon Darkrai's assistance, they do not have the ability to enter the Dream Realms of other people within the region.
It is unknown if Darkrai's counterpart, Cresselia, plays any role in the Dream Realm's existence or management.
Cities, routes, and other locations
