Psychological Horror Short Story Needed

I’d like an original psychological horror/thriller short story that takes place entirely inside an abandoned building. The narrative must stay in a tight third-person limited point of view, tracking a single unwitting visitor as events spiral from unease to full-blown terror. Atmosphere and psychological tension matter more than gore; every detail of the setting should feed the creeping dread and leave readers questioning what is real.

Deliverables
• Complete story, roughly 3–5 k words, in Word or Google-Doc format
• A brief (one-paragraph) synopsis outlining the core hook, climax, and resolution
• Proofread manuscript—consistent tense, no plot holes, ready to publish/submit

I’ll review for pacing, originality, and how effectively the ending lingers. If this sounds like your kind of nightmare, let’s make readers shiver.
