Slumber

Dr. Alice Arnolds is a respected sleep therapist and neurologist whose clinical rationality masks a deep personal trauma from her brother's death. She is skeptical of the supernatural, yet her investigation into the Nocnitsa pushes her to confront guilt and fear. Her intellect drives her to attempt a dangerous dream-merge to face the demon, showing both medical resolve and emotional vulnerability.

Charlie Morgan is the Morgan family’s father, appearing calm at first but becoming violent and withdrawn as night episodes intensify. His body seems controlled during a sleep-induced attack on Alice, signaling the demon's reach into the waking world. The bruises, erratic behavior, and disturbed sleep illustrate the threat’s grip on the family.

Sarah Morgan is the mother who bears the burden of her family’s fear, seeking answers and safety for her children. She shares with Alice the truth about Charlie’s changes and supports dangerous experiments to protect Daniel. Her resilience anchors the family as the supernatural threat tests their sanity and unity.

Emily is the teenage daughter who begins to glimpse the haunting figure, acting as a witness to the creeping horror. Her awareness of the night-haunting presence adds a layer of fear and empathy as the family fights to keep Daniel safe. She embodies the vulnerable but perceptive observer of abnormal events.

Daniel is the young boy plagued by severe sleep disturbances, screaming and thrashing in his room. He describes a dark figure that sits on his chest and drains his life, a victim-turned-carrier for the Nocnitsa. His deteriorating condition drives the investigation and the dream-haunting plot.

Amado is a former sleep expert living off the grid after a mental breakdown, now offering dangerous folklore-based insights. He explains the Nocnitsa’s history and how it feeds on fear, guiding Alice to confront the demon within dreams. His unconventional wisdom becomes crucial to the plan.

Cam is the clinic janitor who appears as a quiet link between the clinical world and Amado’s off-grid knowledge. He nudges Alice toward the elder’s guidance, recognizing the limits of conventional sleep medicine. He helps connect the dots that lead to facing the Nocnitsa.
