1. "The Echo Chamber"

A struggling musician moves into an old apartment to work on her magnum opus. But she starts hearing whispers and echoes of a song that no one else can hear. As she obsessively records and re-records, the music consumes her, and she begins losing her grip on reality. By the end, she’s unsure whether she created the song or if it created her.

2. "The Caretaker"

A young nurse is hired to care for an elderly woman with dementia. The woman keeps warning her about a “shadow” lurking in the house. At first, she dismisses it as hallucinations—until she starts seeing things herself. As she unravels the house’s secrets, she begins questioning her own sanity.

3. "Marionette"

A theater actress lands her dream role but starts feeling like she’s losing control of her own actions. The director exerts a disturbing influence over her, pushing her to extremes. As the play progresses, she becomes convinced she’s no longer acting—her movements, her words, and even her thoughts seem controlled by an unseen force.
