Indie sci-fi horror feature Somnium is set to hit select theaters on August 28 with a Digital release to follow on September 9, with Yellow Veil Pictures revealing a trippy new trailer today.

Starring in the debut feature of Racheal Cain are Chloë Levine (The Sacrifice Game), Peter Vack (Mozart in the Jungle), Will Peltz (Unfriended), Johnathon Schaech (Suitable Flesh) and Grace Van Dien (Stranger Things, Redux Redux).

Somnium follows Gemma, who moves to Los Angeles after a painful breakup with the hopes of making it big:

To get on her feet, she takes a job working the overnight shift at Somnium – a mysterious, experimental sleep clinic where dreams are made real. Meanwhile, Gemma throws herself into the cutthroat world of Hollywood auditions. But as the pressure to succeed mounts, she begins to experience strange and unsettling phenomena, and soon finds herself trapped in a nightmarish spiral as she discovers a darkness lurking within the clinic walls.

Somnium will officially open theatrically Friday, August 29 in Los Angeles, followed by a run in New York City starting September 6. Here's what Cain has to say about the movie hitting theaters:

“I couldn’t have dreamt Somnium would end up in theaters just a few miles from where I started writing it all those years ago. This film has clawed its way into existence over the last decade and I can only hope viewers find it was worth the wait.”

Beginning September 9, audiences across North America will be able to rent or own Somnium on Digital HD, including Apple TV, Prime Video, and Fandango at Home. Check out the new trailer and poster below:
