I made this originally around 2020 and totally forgot about it afterwards.
The world is heavily based off of the backrooms, with the concept of noclipping out of reality.
It was basically my take on how a universe like that would work, where both normal reality co-exists with one that looks extremely similar to one you'd seen in your dreams.

The way it works is basically the same as the backrooms. There’s the normal world, and a dream like reality that humans can only access in very rare “weak spots”. Humans may no-clip out of the world and fall into this dimension, where everything looks rose tinted, almost like a memory you’re struggling to remember.
This world has a functioning society similar to our own, except none of them are human. These species very, but the majority fall into 4 categories: animal like, monster, humanoid, or some sort of fantastical creature. Many residents are combinations of them.
Humans who fall into this reality are often paralyzed and struggle with fatigue, as they are given a new vessel/body to function with. These transitioners are given free treatment in order to help them adjust, since there is seemingly no way for them to turn back.
These individuals gradually lose their memory, and become completely adapted to the dream reality.
This world mostly focuses on this dream world, and the characters who inhabit it. (It’s kinda confusing, I made this a billion years ago, I didn’t really question anything then.)
