6 Souls (also known as Shelter) is a 2010 psychological horror thriller that delves into the unsettling intersection of forensic psychiatry and the supernatural. The film follows Dr. Cara Harding, a skeptical psychiatrist played by Julianne Moore, who takes on a patient, David, portrayed by Jonathan Rhys Meyers, diagnosed with multiple personality disorder.

The plot thickens as she races to unravel the mystery before becoming the next target, blending elements of mystery and dread.

Directed by Måns Mårlind and Björn Stein, 6 Souls builds tension through atmospheric direction and a creeping sense of unease, rather than relying on jump scares.
