Mara (2018)

When one woman is charged with murdering her husband, the only witness is her eight-year-old daughter. And what she saw was her mother killing her father. But things aren't as simple as they might seem at the beginning, which is what Dr. Karen Fuller quickly realizes as she looks into the case. The more she researches, the more it seems as if sleep paralysis may have something to do with the death. And the girl may not have been seeing her mother at all-she may have been witnessing the evil machinations of an ancient demon poised to destroy.
