Dream Grove (DG) is a dungeon that is located in Tanren Undercity. Dream Grove is a time specific dungeon; It will be Daydream when dawn or day and Nightmare when dusk or night. Should the time change to correspond with the other version while the player is in the dungeon, it will change once the player reaches the next floor. Hence players should consider the time before heading into the dungeon if they have a specific version in mind.
See their respective pages for more information on their versions.
Dreamy Clearing

There are a total of six boxes in the room. Without either of the keys the boss drops, you can only get the two Deluxe Boxes. For the other four boxes' items, see the Daydream and Nightmare pages.
