LOS ANGELES — The threshold between the conscious mind and the subconscious is a fragile border, one that horror cinema has long sought to breach. Shudder has secured the distribution rights to Parasomnia, a supernatural horror film written and directed by James Ross II, marking his feature debut. Following its world premiere at the Overlook Film Festival earlier in 2026, the film is scheduled for an exclusive streaming debut on September 4, 2026.

Beyond the Retread

Ross II approaches the genre with a distinct philosophical anchor, citing Wes Craven’s A Nightmare on Elm Street not as a template to copy, but as a proof of concept for the universality of dream-based terror. In interviews regarding the project, the director emphasized a desire to elevate mundane, involuntary human experiences—specifically the helplessness of sleep—into a source of profound dread. The goal, he noted, was to craft an immersive psychological horror experience that diverges from direct homages, focusing instead on the visceral anxiety of the body betraying the mind.

The narrative centers on Riley, a young woman grappling with severe night terrors and unresolved trauma. When her best friend vanishes under mysterious circumstances, Riley begins to suspect that a demonic entity, once confined to her dreams, has crossed the veil into the physical world. This premise allows the film to explore the erosion of reality, a staple of the psychological horror subgenre, while grounding the supernatural elements in the character’s specific emotional wounds.

Ensemble and Atmosphere

The production features a cast committed to the film’s tense atmosphere, including Jasmine Mathews as Riley, alongside RJ Brown, Sally Stewart, Stephen Barrington, Danny Brown, and Simon Longnight. Their performances are designed to support the film’s central tension: the paranoia that one is never truly safe, even when awake.

Shudder has released an official trailer to coincide with the announcement, offering a glimpse into the visual language Ross II has developed. The footage highlights the film’s supernatural elements and the creeping dread that permeates the narrative, serving as a promotional tool for the upcoming premiere. By leveraging the platform’s established audience for elevated horror, Shudder positions Parasomnia as a significant entry in the independent horror landscape of 2026.

As the streaming platform continues to cultivate a space for indie horror that prioritizes atmosphere and psychological depth over cheap shocks, Parasomnia represents a careful balancing act. It must satisfy the genre’s demand for scares while fulfilling Ross II’s artistic ambition to make the ordinary terrifying. For viewers accustomed to the structured terror of festival circuits, the September premiere offers a chance to see how a new voice interprets the ancient fear of the dark.
