“Backrooms” has finally arrived on streaming, just under two months after the horror movie made its theatrical debut. Based on Kane Parsons’ viral YouTube horror series, the film expands the internet phenomenon into a full-length nightmare, following a therapist who ventures into an endless, terrifying dimension after a strange doorway beneath a furniture showroom leads to the mysterious Backrooms.
What started as a creepy online concept inspired by the infamous Backrooms creepypasta quickly became one of YouTube’s biggest modern horror sensations, with Parsons’ unsettling found-footage videos building an entire mythology around the mysterious space.
But even after bringing the story to the big screen, “Backrooms” leaves plenty of questions unanswered. From the true origins of the dimension to the strange creatures hiding within it, fans (like me) have spent countless hours trying to piece together what it all means. So, here are five fan theories that could change how you see the movie.
1. The Backrooms are actually a giant machine scanning reality
This first theory says the Backrooms are not just an alternate dimension, but a giant living machine that scans and recreates physical objects and human memories. The idea comes from the reveal that Async Research Institute, before discovering the Backrooms, created MRI machines. Fans believe the dimension may have been accidentally created by Async’s electromagnetic experiments, or that it copied the technology of the first human machine it encountered: an MRI scanner.
Fans believe this explains why many creatures in the Backrooms appear incomplete or distorted. Like a blurry MRI image, the dimension may be recreating living things incorrectly, using materials around it. The original yellow corridors may have been created during Async’s first experiments in the 1970s, when a solar flare disrupted their technology and shaped the environment.
Because Clark spent so much time inside the Backrooms, the dimension may have created a much more detailed copy of him. This could explain why the Captain Clark entity is different from other creatures, with a human-like body, organs, a brain, and even real blood.
2. Clark created the Backrooms without realizing it
The Backrooms could actually be a physical representation of Clark’s fractured mind, similar to the psychological horror of House of Leaves. As a failed architect struggling with alcoholism and denial, Clark’s broken subconscious creates the endless maze of distorted rooms and impossible corridors.
The Still Life creatures are believed to represent different parts of Clark’s suppressed memories and guilt. Some reflect people he has hurt or forgotten, while the red-haired entity may represent his ex-wife Barbara and the pain caused by their failed marriage.
The Captain Clark monster represents Clark’s “Shadow”, embodying his anger, ego, and refusal to accept responsibility. The entity remains peaceful while Clark embraces those darker traits, but becomes violent when Clark tries to save Mary, showing he is finally rejecting that part of himself. The Backrooms ultimately become a battle between Clark’s desire to change and the destructive version of himself he created.
3. Captain Clark existed before Clark ever entered the Backrooms
One interesting theory suggests the Backrooms exist outside normal time, creating a loop where future events can affect the past. The idea connects to the web series, where characters experience strange time shifts and events happen out of order.
The biggest evidence is Captain Clark appearing in Async footage before Clark ever enters the Backrooms. Fans believe the dimension used recordings and memories of Clark to create the monster before he physically arrived, causing the creature to exist earlier in the timeline.
The dead seagull seen during Clark’s exploration also supports this theory, as it appears alive in earlier footage, suggesting time works differently inside the Backrooms. A similar idea applies to Bobby’s death. The white shirt he finds may belong to a future version of himself, meaning the creature that kills him could be his own decayed copy.
4. The Clark we see at the end isn’t the real Clark
My favorite theory at the moment is that Clark and the Pirate Clark monster may not be who we think they are. It argues that the Clark who kidnaps Mary near the end of the film is actually a highly advanced Still Life copy, while the terrifying Pirate Clark creature is the mutated form of the original human Clark (a bit confusing, I know).
The biggest clue is Clark’s forehead scar. The human Clark has the scar throughout the movie, but the version Mary meets later is missing it. However, the Pirate Clark monster has the same scar, suggesting it may be the real Clark transformed by the Backrooms.
According to the theory, the dimension slowly altered Clark’s body while creating a copy based on his memories and behaviors. Because the replica was imperfect, it missed small details like his scar. This means Pirate Clark attacking the fake Clark could actually be the original destroying a false version of himself.
5. Mary never escaped the Backrooms
The horror of Backrooms could extend beyond the yellow corridors, with the Async Research Institute itself being part of the trap. Instead of a real facility, the clean and futuristic building Mary wakes up in could be a simulation created by the Backrooms.
The theory argues that, after years of Async researchers entering the dimension, the Backrooms collected enough information to recreate the facility, including its layout, documents, and employees. The real Async headquarters may have been consumed by the anomaly long ago.
In this interpretation, the fake facility acts as an illusion designed to make humans feel safe and stop questioning their surroundings. By keeping people calm and contained, the Backrooms can study their memories and behavior. The final act may not represent Mary escaping the nightmare, but entering an even more advanced layer of the same mysterious dimension.
