One in five will experience the terrifying phenomenon of sleep paralysis. Victims wake to find that they are paralyzed and unable to move or speak. Many experience frightening visions of demons, shadows, or an old woman known as The Hag. For others there is simply the unmistakable presence of evil. In extreme cases, these potentially supernatural attacks can occur for decades. Overwhelmed, exhausted, and entirely alone, victims can lead shattered lives dominated by the fear of social stigma. Those who seek medical advice are often misdiagnosed and labeled psychotic or schizophrenic. In Your Worst Nightmare: Supernatural Assault Soul Smack explores the surprisingly common and greatly misunderstood phenomenon of Sleep Paralysis. In this ground breaking documentary, Soul Smack interviews actual victims, consults with experts, and offers advice on how to live with what might be your worst nightmare.
