Psychological Horror Short Story

I want to commission a tightly-written psychological horror short story that leaves readers unsettled long after the last line. The narrative should rely on tension, unreliable perceptions, and creeping dread rather than overt gore.

Scope
• Length: an agreed-upon short-story range (roughly 3,000–6,000 words; we can fine-tune once we outline).
• Tone: claustrophobic, slow-burn suspense that escalates to a shocking but believable climax.
• Originality: no tropes lifted directly from existing works—fresh twists only.
• Delivery format: editable file in Word or Google Docs, with standard manuscript formatting.

Acceptance Criteria
• A complete story arc with a protagonist whose sanity—or perception of reality—erodes convincingly.
• Psychological horror elements must drive the plot; any supernatural hints should remain ambiguous unless we decide otherwise during outline approval.
• One round of revisions after my initial read-through to polish pacing, characterization, and atmosphere.

Once we agree on a one-paragraph pitch, you’ll draft a concise outline for sign-off before writing the full piece. Please share a brief sample or link that showcases your horror or dark-fiction style so I can confirm the voice matches the mood I’m after.
