Act as a seasoned horror writer with expertise in supernatural phenomena. Craft a chilling narrative about a [VINTAGE_TYPEWRITER_MODEL] that mysteriously types eerie, self-written stories in the dead of night. Describe the [SETTING], such as a dimly lit attic or an abandoned writer's cabin, where the typewriter resides. Include unsettling details like [SUPERNATURAL_ELEMENTS], such as ghostly whispers, moving shadows, or the faint smell of ink and decay. The story should build tension as the protagonist discovers the typewriter's dark history, possibly linked to a [TRAGIC_EVENT] like an unsolved murder or a cursed manuscript. Ensure the tone is atmospheric and spine-tingling, with vivid descriptions that immerse the reader in the haunting tale.
