Urban First-Person Horror Short Story

I need an original psychological horror short story told entirely in first-person, unfolding in a contemporary urban environment. Think cramped apartments, flickering streetlights, and the subtle paranoia that builds behind every locked door. I want the dread to come primarily from the narrator’s unraveling mind—unreliable memories, intrusive thoughts, and creeping self-doubt—rather than overt monsters or excessive gore.

Target length is 5,000–8,000 words. Tone should be tense and atmospheric, steadily tightening until the climax delivers a lingering chill. Dialogue must feel natural to a modern city setting, references current technology realistically, and keeps pacing brisk without sacrificing character depth.

Deliverables:
• Complete manuscript in .docx or Google Docs format
• A brief synopsis (150–200 words) outlining core plot beats
• One round of revisions after initial feedback

Acceptance criteria: the piece stays in first-person throughout, is set unmistakably in a modern urban locale, and sustains psychological tension without relying on jump-scare clichés.
