As of version 0.095g, endings have been implimented into Yume 2kki. The ones currently found are listed below.
Note that all of these endings require you to drop your effects at Urotsuki's Dream House. To do this, equip an effect in the trophy room, go up to the pedistal that corresponds to the effect, and then drop it.
<WARNING: ENDING SPOILERS AHEAD. DO NOT READ UNTIL YOU HAVE COLLECTED ALL THE EFFECTS. THE VIDEOS SHOW THE ENDINGS.>.
If you get all 5 endings, you will get a effect "key". At that time you will be able to open the door in the reality. Go through the utility room and press Z in front of the key hole, you will be transported to the authors' room.
Ending #1
This ending can be seen by pinching your cheeks while awake. The screen will then fade to black,thumb|right|300px|Ending #1: Books
and Urotsuki will be stuck in a black screen. Pinching your cheeks again will cause her to wake up in her room, with books lying all around her. Pressing Z or X causes Urotsuki to get up. She walks over to the shelf on the left, puts the books away, then proceeds to leave the room.
NOTE: You need to drop items now, on versions older than 0.97c you didn't need to drop the items.
Ending #2
This ending can be seen by going into the Trophy Room in Urotsuki's Dream House and dropping all of your effects, then waking up. Once you do, save and check outside on your balcony. There should now be a staircase there, and if you walk up to it, she'll climb up the staircase. But, don't actually jump off. Go back down, and she'll throw it off the balcony, rid of it forever.

The next shot shows us Urotsuki as she finally opens the door, and proceeds to go outside. Then a new credit sequence rolls unlike the others: Urotsuki is on her Bike effect, passing by some other characters she's met through her adventure. It ends with her getting off her bike, and walking into a house.
This is likely the good ending to the game, or the true one.
Ending #3
This ending can be seen by going into the Trophy Room in Urotsuki's Dream House and dropping all your effects. Then, wake up. Once you wake up, you'll find the same thing Madotsuki did: A staircase, leading off of her balcony. If you walk up next to it, she'll climb to the top. Press X, and Urotsuki jumps.thumb|300px|right|Ending #3: UFO Game
While she's falling, other characters you've met throughout the game will appear around you, with strings attached to some of their heads. Then it fades to black with a big THUD....And it turns out she had been in a claw grab game the entire time, and Urotsuki herself was a small plushie! A small schoolgirl wins Urotsuki, and then runs off with her. The next shot is of the girl sleeping, with Urotsuki, as a plushie, sitting on the floor next to her. Then the scene fades.
Ending #4
This ending can be seen by collecting 155 wallpapers of the total 157, going into the Trophy Room in Urotsuki's Dream House and dropping all of your effects, then waking up. Go to the balcony and you find the ladder is not on the left, but in the middle. Walk up and climb the ladder, you'll see a train coming to you, and a black human-like creature invites Urotsuki to take the train. Then the train runs in the space, with the credit sequence rolling below it. The last shot is of Urotsuki sitting with the black creature, and the text "Fin" located at the bottom-right. thumb|300px|right|Ending #4: Train Ride
Ending #5
You cannot see #5 as of v0.099f yet (Numbering of #6 is irregular).
Ending #6
This ending can be seen by seeing events in the hidden rooms of Flying Fish World, Rough Ash World and Green Neon World and then going to the balcony. This ending is not added to ending lists.
Ending #---
This ending can be seen by collecting over 95% over the game's music, going into the music menu, and listening to some tracks. When you exit the Computer screen,you may be returned to a variation of Urotsuki's Room, with the curtains drawn, blocking the balcony, and the front door open. Walking outside will take you to the music room, with a phonograph and a bed in the middle of the room. Getting into the bed and falling asleep will slowly fade the screen to a dark blue, and the credits will roll, with the phonograph playing a lullaby version of the theme in the background.
Glitch Ending
This ending can be seen by sleeping in the bed in the bedroom of Urotsuki's Dream Apartments, with a 1 in 64 chance of taking you to a bleak, desaturated version of the bedroom, apparently set sometime in the future. Although The TV, Console and Computerare broken, interacting with the computer has a 1 in 10 chance of taking her to a smaller bedroom, similar in appearance to her own. Sleeping in her bed again will lead you to an even more desolate version of Urotsuki's bedroom; this version appears utterly abandoned and ravaged by time. All the objects in the room are broken, but the front door is now unlocked and leads to a forked hallway. Heading down the eastern corridor will take you to a dark, sinister room with many beds. Sleeping on the bed in the middle will trigger the "fake" ending sequence, with a credits roll riddled with graphical artifacts and glitchy, dissonant music. Afterwards, Urotsuki will wake up next to her bed in her real bedroom.
