“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

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
