Level -0 is unknown whether to be a sub-level, a level, or an entity of the backrooms.
At the moment, let's just call it the sub-level of Level 0, The Void, and Level -1.
Description:
This image was taken via a wanderer, who dreamed of fishing with his father like he used to.
"Level -0" resembles something, or somewhere, similar to something you've seen in your dreams. You feel some sort of comfort when your in this level, and the level always replenishes you of needed nutrients, supplies, etc. The level has no harmful entities, just "scary" entities that are meant to scare you. The level always has a calming, simple melody always playing and people say for this to be the "safest" level of the backrooms. A redditor with the name of u/InLevel-0 has a video and some images of his “dream”
This "level" has a mind of it's own, and it's said to like to be called "Yume" which can mean "Dream" or something around those lines. The level has a slightly feminine voice, although it likes to be called they/them, Yume, or he/him. The "level" sometimes may present a figure, with a feminine build. This figure will have medium-long hair, which is brown with a beige strip down towards the tip of a big cluster of piece which covers their nose. The figure's face is covered by a paper mask of a sort. Also, Yume would rather keep her face a secret, so please, DONT TAKE IT OFF
When one first enters "level -0", it will look like a completely white space, with no sounds, textures, anything. As you continue through the "level", the melody will begin to play as your dream(s) are "loaded" in. Most dreams consist of (but not limited to):
》Flying within a beautiful night sky
》Alone in a city, with merely your thoughts and such to keep you company.
》Sitting on a hill with a loved one.
》Your home
》Etc.
People cannot die in the "level", seeing as how when they die, the "level" revives them and says encouraging messages such as:
》"You did the best you could, everybody you know would be proud."
》"You just got unlucky, that's all!"
》"Your family loves you, so does Yume!"
》"I believe in you! Do better than last time!"
These quotes are in a soothing, slightly feminine voice and are also are stated when the person within the "level" have horrible self-esteem or are insane, helping them boost self-esteem or regain sanity. This level has an abundance of Yume's Water and Yume's Cooking, which taste just like your mother's best dish.
The level, and Yume, both have something about them, which was found out via asking them-
Sorry about this, someone must've changed some things! Let me fix that...
...and done!
-Yume and the "level" are just calming and peaceful, meant to be a "break" from the backrooms for you to...blow off steam, have friends, talk to someone, FEEL LOVED BY YUME AND YUME ONLY, and more!
Entities:
There are no "entities" but one can consider Yume an entity.
Yume's height seems to be around 5-5'2 feet tall, with a orange hood on that covers their knees. They don't wear shoes most of the time, although one might see them with slippers on. Their skin is a white tone and they have a brown+baige hairstyle. One of Yume's biggest challenges is making friends, seeing as how most people believe they are an entity, run away. Yume can enter and exit other levels to their will, but prefers to stay in this level. They are supposedly friends with The Record Keeper, stating them to be "Their big big bub". They have almost a child-like innocence and give wanderer's a comforting feeling, almost as they escaped and saw their mother again, when they are near. They are said to have extreme hyper-regeneration, as well as abnormal human physiology. Some of their favorite games are Minecraft, Animal Crossing, and Super Smash Bros.
Yume is a very clingy person, who seems to like the "cakes" in Level Fun. They mostly spend their time in Level -8 because her favorite movie usually plays when she enters the level, The Little Mermaid. Yume really, REALLY likes cooking, also!
Colonies:
Yume hides all other humans, so you can be alone with your thoughts, and with Yume! :D
Entrances and Exits:
One can enter the level by falling asleep in any level with a chance of being sent here.
One can also enter via "No-Clipping" through The Void, but this is unconfirmed.
To leave, just fall asleep. When you do, you'll wake up in one of the many peaceful levels in the backrooms, just remember to say thank you and goodbye to Yume. One can also type "HowDidItComeToBe.exe" in The End.
