Perhaps a creepy ghost story. Or maybe an ominous tale of demonic possession. Or more scientifically, is this a twisted tale of a journey into the mind of a young girl struck with Dissociative Identity Disorder? 2015's "Anguish," based on true events is heavy on the creepy, and our beset protagonist is a spitting image of a young Linda Blair. In fact, much of this film will remind you of segments of "The Exorcist," and maybe a little of "The Evil Dead."
