Into the Backrooms: The Internet Horror Phenomenon Explained Before the Movie Arrives

If you’ve never heard of the Backrooms before, the easiest way to understand it is this: imagine accidentally stepping out of reality and into an endless maze of empty yellow rooms lit by flickering fluorescent lights. The carpet is damp. The walls are stained. There are no windows, no exits, and no clear explanation for where you are. Something may also be wandering the halls with you.

That simple idea became one of the internet’s most influential horror concepts of the last decade.

The Backrooms began in 2019 when a single unsettling image appeared online: a photo of a bland office-like space with yellow wallpaper and harsh lighting. Users on forums and social media built a mythology around it. According to the lore, people can “no-clip” out of reality—a term borrowed from video games—and fall into the Backrooms by accident. Once trapped, they wander through endless interconnected rooms that feel both familiar and deeply wrong.

What made the concept explode in popularity was not gore or jumpscares. The fear comes from the atmosphere. The Backrooms taps into something psychologists sometimes call liminal space anxiety: the discomfort created by places that look ordinary but feel abandoned or unreal. Empty malls after closing time, silent school hallways during summer, hotel corridors late at night—the Backrooms turn that sensation into a nightmare.

Over time, internet creators expanded the mythos into hundreds of “levels.” Some are empty office mazes. Others resemble flooded basements, abandoned playgrounds, industrial tunnels, or infinite suburban neighborhoods. Certain levels supposedly contain creatures, while others drive people insane simply because of their isolation and repetition. The lore became collaborative, with thousands of users contributing stories, maps, survival guides, and fictional scientific documents.

The Backrooms moved from niche internet horror into mainstream culture largely because of Kane Parson, also known online as Kane Pixels. In 2022, Parsons released a series of found-footage style videos on YouTube that depicted explorers trapped inside the Backrooms. The videos looked unusually realistic and cinematic despite being created largely with consumer tools and visual effects software. They quickly went viral and helped redefine internet horror for a new generation.

Now the concept is becoming a major theatrical film. Backrooms is scheduled for release on May 29th and is directed by Parson himself. The movie stars Chiwetel Ejiofor and Renate Reinsve, with distribution by A24, the studio known for psychologically driven horror films. Early descriptions suggest the story follows a therapist searching for a missing patient who disappears into the Backrooms.

One reason audiences are interested in the film is that the Backrooms concept translates unusually well to cinema. Traditional horror often relies on monsters or violence. Backrooms horror is more existential. It is about disorientation, isolation, repetition, and the fear of being trapped somewhere outside normal reality. Reviewers covering early reactions have described the movie as deeply atmospheric and psychologically unsettling rather than conventionally scary.

The movie also represents a major shift in filmmaking culture. Parsons began as a teenager making internet videos, yet now directs a large-scale studio horror film before the age of twenty-one. Critics and commentators have pointed to the project as evidence that online creators are increasingly reshaping mainstream entertainment.

For viewers going into the movie without prior knowledge, the most important thing to understand is that the Backrooms is intentionally mysterious. There is no single official explanation for what the place really is. Different stories describe it as a parallel dimension, a glitch in reality, a government experiment, or something beyond human understanding entirely. The ambiguity is part of the appeal.

So when the film opens on May 29th, do not expect a conventional haunted-house story. Expect a slow descent into an impossible space where the ordinary becomes terrifying simply because it never ends.
