Netflix documentary The Devil On Trial has a brief segment that mentions how a drug called Sominex might have been a key ingredient in explaining the mysterious events of the central trial, making it hard not to wonder what the drug actually does. Based on a true-story that inspired the story of The Conjuring: The Devil Made Me Do It, The Devil On Trial explores the events surrounding a murder trial where a demonic possession was used as defense. Apart from walking viewers through the trial and the central Glatzel family's paranormal experiences before it, the documentary also highlights how the renowned demonologists Ed and Lorraine Warren were also involved in the case.
