The Backrooms is a famous urban legend and online horror topic. It began with a disturbing post on 4chan in 2019 and has since acquired substantial traction among internet forums. The Backrooms are sometimes characterized as a large, apparently infinite succession of repetitive, poorly lighted rooms, corridors, and halls that lie outside of our regular world. The tale behind it generates emotions of dread and surrealism, and it has grown into a bigger "creepypasta" (a kind of horror-related material that is extensively shared backrooms online).

Backroom Concept and Setting:

The Backrooms are sometimes characterized as an infinite labyrinth of yellowish rooms with ancient, discolored carpets, flickering fluorescent lights, and a continual hum from the lights.
The design is repetitious and unsettling, giving the impression that you're wandering in circles with no obvious exits or openings to the outside world.
The walls are characterized as having an uncomfortable, fading beige-yellow color that gives the space a dismal, depressing aspect.
How Does One Get There:

The most prevalent misconception about the Backrooms is that you may "noclip" out of reality, akin to a video game malfunction, and accidently fall into them. "Noclipping" means going through solid things or barriers (such as walls) that are typically inaccessible.
Once you're in the Backrooms, there's no getting out. It is defined as being stuck in boundless space with no way out.
The Levels:

The notion of the Backrooms has evolved throughout time, and individuals have come up with their own ideas about what they may hold. These "levels" differ in terms of appearance and threat. For example:
Level 0: The "main" Backrooms, including countless rooms, yellow walls, and buzzing lights.
Level 1: Described as darker and more industrial, with weird equipment, leaks, and potentially aggressive creatures.
Level 2: Narrow, gloomy halls with potentially deadly settings and animals hiding in the shadows.
Levels 3 and up: There are many further levels in fan fiction and debates, including more creepy or surreal surroundings like woods, workplaces, or even more fanciful situations.
The dangers:

The Backrooms aren't only a spooky, unpleasant environment; they also house a variety of dangers:
Entities: There are legends of strange, sometimes aggressive entities that live in the Backrooms. These entities might vary from humanoid forms to weird and ugly creatures.
solitude: The sensation of solitude and the limitless nature of the chambers may drive individuals insane, causing mental exhaustion.
Time and Space Distortion: Time and space are supposed to fluctuate erratically in the Backrooms. What seems to be a few minutes might quickly become hours, and you may never realize how long you've been there.
Popular Media:

Backrooms have become a popular trope in horror literature, web videos, and even video games. You may discover creepypasta tales, YouTube videos, and even games that entail navigating the unending labyrinth of the Backrooms.
Kane Pixels' short film "The Backrooms (Found Footage)" went viral and is one of the most well-known YouTube films that promoted the Backrooms. The film showed the eeriness of the Backrooms from a first-person viewpoint.
Several independent games have also been created about escaping or surviving in the Backrooms, stressing the terror of being confined in such a location.
The Backrooms appeal to fears of the unknown, claustrophobia, and the eerie, creating a familiar but unpleasant experience. The concept of being stuck in an unending, unchanging space with no obvious way out is a potent psychological terror. The image of unending, repeated areas also taps into the fear of solitude and disorientation.

In summary, The Backrooms is a disturbing fictional world where humans are stuck in a maze-like setting that exists outside conventional reality. The experience is characterized as weird, unpleasant, and creepy, with no obvious way out, making it an unsettling notion for aficionados of horror and the unknown.
