- For the variant during dusk and night, see Dream Grove (Nightmare).
Daydream Dream Grove (DG Daydream, DDG) is a dungeon located in Tanren Undercity that is only accessible at dawn and day. It will change to Nightmare Dream Grove should the player enter a new floor at dusk or night. The dungeon has mostly Fairy- type Pokémon, but also has a number of Normal- and Psychic-types as well. Though Altaria and Lickilicky spawn throughout all the floors, so expect it to be clear most of the time too.
A 
Whimsical Key, obtainable from Nightmare Dream Grove, is required to complete the entire dungeon.

Dream Passage
After the mini-boss is a break point. You spawn in an enclosed room with a warp and door. To open the door in front, you need the Whimsical Key dropped by the midboss in the Nightmare version of Dream Grove. If you don't have the key, the warp takes you out to the Central Fork of Tanren Undercity. This map is instanced, meaning every member in a party will need to bring their own key.
Beyond the door is another room with a locked door. On the left of this room is a warp leading to the Royal Garden. Once you get a Garden Key from there, you can pass the next door and access the storage and move on when ready.
Royal Garden
The player must go through this warp puzzle to grab the Garden Key to open the locked door in the Dream Passage to progress further into the dungeon. If the player uses 
Honey in this room, one Spritzee or Swirlix will spawn, but this entirely depends on ID of the player using the Honey.
Bosses
Gengar, Umbreon, and Banette
Upon leaving Floor 30, you will come across a team consisting of Gengar, Umbreon, and Banette, who are having a tea party.

They know the following moves:
- Banette: Embargo, Grudge, Phantom Force, Shadow Claw
- Gengar: Energy Ball, Focus Blast, Shadow Ball, Sludge Wave
- Umbreon: Assurance, Confuse Ray, Helping Hand, Moonlight
Boss drop:
Mischievous Key (Gengar)
Dialogue:
- Gengar: Oi, yer giving me the creeps just standing there, lookin' 'round. Siddown, pal.
- Banette: What a surprise. Never thought I'd see the day Alice would join our little tea get together.
- Umbreon: Pft... If that's Alice, then I'm a blue caterpillar. C'mon, you're not that gullible, are you?
- Gengar: Guess yer a blue caterpillar then, Umbry, cause this is definitely Alice.
- Gengar: Yer Alice, ain'tcha?
Yes- No
- Gengar: You sayin' you ain't Alice? Yer name's [Player Name]?
- Gengar: No need to lie to us just because we ain't like all sunshine and happiness like everybody else 'round here, Alice.
- Umbreon: Tch... How convincing.
- Umbreon: Whatever. Tea's getting cold.
- Gengar: Rightyo, bro.
- Banette: Should we offer some of our tea to... Alice?
- Umbreon: Idiot. Why would Alice want to drink tea with riff-raff like us?
- Banette: Awh man, you don't gotta say it that. Yer right though.
- Gengar: Say, you guys know we ain't do nuffin' wrong, right?
- Banette: Sure feels like it; 'specially with how the cutesy Pokémon 'round here treat us.
- Banette: But hey, let's just drink our tea. We don't want Alice to feel left out.
- Gengar: Left out, huh... What about us, eh? Darlin' sweet Alice don't gotta be left out though, hm?
- Gengar: Perfect little Alice gets the best of two worlds while we're being outcasted.
- Umbreon: ...
- Banette: ...
- Gengar: Say, Alice... Let's play a game, yeah?
- Gengar: Alice is 'pposed to be super strong, right? We should put that to the test to see if you're really Alice, darlin'.
- Umbreon: Yeesh... Yeah, that's gotta be Alice.
- Gengar: Told ya.
- Gengar: I oughta apologize. Umbry there still had some doubts 'bout ya. So we kinda made up a reason to test ya out.
- Gengar: Stressin' that kinda, 'round here we're kinda... not well liked at all. The rulers of this world think we're too crude 'pared to their subjects.
- Banette: There's somewhere out there for us, though. There's just gotta be.
- Umbreon: 'Course there is. That's why Alice is so important. Alice has the power to travel between the worlds.
- Umbreon: Our world is the one opposite to this one. It's... where we belong.
- Gengar: Y'see that there key I dropped when you whammed me real good? It's pretty special.
- Gengar: Had it since I was a Gastly. Ain't got a clue where it came from.
- Gengar: I... think it's from our home world. Ay, don't look at me like I'm spouting some illuminati junk, man.
- Gengar: Look, just take it, aight? You're Alice, ain'tcha? You can travel between the worlds. See if it opens anything for ya over there.
- Umbreon: Ay... Alice. Knock some sense into 'em, would ya? Teach 'em that they can't just depokemonize us because we're different.
- Umbreon: Honest, the two of them are insane with their power. Before they took over, we got along with the... cute things of this world.
- Banette: Yeah... But beat them up for the cute things too. I've heard stories of them jailing almost anyone for no reason.
- Gengar: Well, that's all. We've really got to get goin' now. Tea's probably frozen by now, but we ain't that picky. Any tea is good tea. Even if it's different.
Aromatisse and Slurpuff
The main bosses include Aromatisse and Slurpuff. Before challenging the player, Slurpuff reveals that it thinks that the player is messing up the good vibes according to a conversation with Aromatisse. This leads to a battle in which when they are defeated, Slurpuff accepts that not everyone leads to bad vibes. Then it will try to let everyone in.
They know the following moves:
- Aromatisse: Heal Pulse, Misty Terrain, Moonblast, Reflect
- Slurpuff: Energy Ball, Light Screen, Play Rough, Wish
Boss drop:
- Daydream Key (Slurpuff)
Dialogue:
- Slurpuff: Yay! You've finally come, Alice!
- Slurpuff: Late, late, late, though! You should have a timeout for making us wait this long!
- Slurpuff: Oh well though. No time for that! There's waay more punishments in store for ya already!
- Aromatisse: Sweet stuuuuff, before we make Alice go bye-bye haven't you noticed it's a bit quiet? Where's our little rascals?
- Slurpuff: Shhh, dear! I'm trying to decide Alice's punishment!
- Aromatisse: But... Our little angels have gone missing!
- Slurpuff: They're probably just in the garden, now shhhh! Trying to be menacing isn't easy when you're a ball of cotton candy.
- Slurpuff: Anyhow! Alice! You saw those crude, dark things didn'tcha? Aren't they absolutely dreadful?
- Slurpuff: Aren't they just terrible? They're ruining my cute and fluffy pink aesthetic!
- Slurpuff: But... They aren't the only ones, y'know? Alice, you don't belong here either. Really messin' up my good vibes.
- Slurpuff: Which is why Aromatisse and I will have to purify ya! Don't worry, it'll only hurt a lot!
- Slurpuff: W-what? How'd ya beat me? Your team is so offbeat!
- Slurpuff: You guys are so mismatched it's not even funny! You're not even following an aesthetic! Like, I can't even.
- Slurpuff: But you still beat us? Even though we are totes in sync and totally unified and unite---.
- Slurpuff: Nah... We aren't. Well, we are, but we kinda aren't We are just too alike.
- Slurpuff: I think I get it now. We're just too similar and being too similar leads to soft spots.
- Slurpuff: I guess we need different Pokémon to complement each other, huh? How else are we gonna cover up our flaws?
- Slurpuff: Alice, I guess you're the one with good vibes and a real aesthetic.
- Slurpuff: I... will let the crud--- acceptably different things... back into the kingdom.
- Slurpuff: Not only them though. Anyone with good vibes will be welcomed. ...Maybe even if they have bad vibes. I'll try to let them in.
- Slurpuff: Hey, Alice. Thanks. I learned a lot today, like not being afraid to accept those different from me!
- Slurpuff: Anyways, let's get going sweet beak! We've got a party to attend~
