Slumber

In "Slumber," a sleep doctor named Alice (Maggie Q) is forced to confront a parasitic demon that feeds on people's nightmares. This entity, known as the nocnitsa, paralyzed its victims while they sleep, making them helpless against its attacks. As Alice tries to protect a family from this supernatural threat, she must also confront her own demons and the trauma of her younger brother's mysterious death. With the help of her husband Tom (Will Kemp) and a group of experts, Alice must find a way to defeat the nocnitsa and free her patients from its grasp. But as she delves deeper into the nightmare world, Alice realizes that the demon may be more powerful than she ever imagined.
