In “Parasomnia,” a stylish horror/thriller from director William Malone (“House on Haunted Hill,” “Masters of Horror,”) Laura Baxter is a young woman, literally a “sleeping beauty,” who suffers from a medical condition called “parasomnia.” A childhood accident victim, she is actually sleeping her life away, awakening briefly on rare occasions. Art student Danny Sloan falls in love with her, unaware that her hospital neighbor, a terrifying mass murderer and mesmerist named Byron Volpe has other, more sinister plans. Sloan helps Laura escape from her hospital prison only to discover that Volpe is about to enter her dreams.
