-It was between my bedroom and bathroom. Old oak wood, brass handle, slightly warm to the touch.
-I opened it. Behind the door was my apartment. Identical. Same furniture, same coffee stain on the carpet, same photos on the wall.
-But the windows showed a city I didn't recognize. Taller buildings, darker sky, streets that curved wrong.
-On my couch, someone was sleeping. Wearing my clothes. I stepped closer. They had my face.
-I backed out quietly and closed the door. My hands were shaking. I checked again an hour later. The door was gone.
-This morning I woke up on my couch. I don't remember falling asleep there. Through my window, I see that same unfamiliar city.
-The buildings are taller now. The sky is darker. Behind me, I hear a door opening. A brass handle turning.
-I turn around. Someone is standing in a doorway that wasn't there before. They look confused. They look like me.
-They're looking at the couch where I'm sitting. I understand now. I understand what happened to the person who was sleeping.
-I'm the one who was sleeping. And now someone else has opened the door.""",

-He told me when he reached the top, he found himself at the bottom. But everything was different. The trees were taller. The sky was a different shade of blue.
-Most importantly, time had moved forward. He'd been gone for three days. But he'd only climbed for ten minutes.
-Last week, my grandfather disappeared. He left a note in his handwriting. 'I'm going back up. I need to find out where I went. Don't follow me.'
-The police searched for days. They found nothing. No trace. Like he'd never existed.
-Today is exactly one week later. I'm standing at the bottom of the staircase. I shouldn't be here. I know I shouldn't.
-At the top of the stairs, I see someone. They're young. Maybe twenty-five. They're waving at me. Beckoning me up.
-I squint. They look familiar. I realize with ice in my veins, it's my grandfather. Young. The age he was in 1952.
-Behind me, I hear footsteps. I hear breathing. I hear my own voice, sounding older, weathered. It's warning someone.
-'Never climb those stairs,' my voice says. I turn around. There's a young person standing there, looking at me with wide eyes.
-They look exactly like I did when I was twenty-five. Like I looked this morning in the mirror. I open my mouth to warn them.

-I timed it with a stopwatch. Recorded it with my phone. Every mirror. Every reflective surface. Exactly two seconds. Never more, never less.
-Three weeks ago, something changed. I was brushing my teeth before work. I looked up at the mirror.
-My reflection was smiling. I wasn't smiling. I was tired, anxious about a presentation. But my reflection was grinning.
-Then it spoke. I saw its lips move. Two seconds later, I heard the whisper behind me. Right behind me. 'I can see what you're about to do.'

-Six months ago, I noticed camera 247 was offline. Floor 21, east hallway. I went to check it. The camera was fine.
-But when I reviewed the footage, I saw myself walking down that hallway. Checking the camera. Exactly as I'd just done.
-The timestamp said 3:47 AM. My watch said 3:52 AM. I'd checked the camera at 3:50 AM.
-The footage showed me checking it two minutes before I actually did. That's impossible. That's not how time works.
-I started checking the other cameras obsessively. Looking for anomalies. Glitches. Proof that the system was broken.
-Last night I found something worse. Camera 156. Floor 13. Except we don't have a floor 13.
-The building was constructed with twelve floors, then fourteen, fifteen, and so on. Superstition. Standard practice.
-But camera 156 shows a floor. Empty offices. Dust-covered desks. Calendars on the walls showing dates from 1979.
-On every screen, the same image. But camera 156 shows something else. Shows somewhere else. A floor that doesn't exist.
-Tonight, I'm going to find it. The elevator only goes to floors 1 through 12, then 14 through 30. But there's a service shaft.
-I'm in the shaft now. Between 12 and 14. There's a door here. It's been welded shut, then painted over. Someone didn't want it opened.

-They're all showing me. Right now. Sitting at my desk. Watching camera 156. I'm in two places at once.

-    ## 🚀 Deployment Guide
-    
-    ### HuggingFace Spaces Setup:
-    
-    1. **Create Space:** https://huggingface.co/new-space
-    2. **Settings:**
-       - SDK: Gradio
-       - Hardware: **GPU A10G or T4 (required)**
-       - Space name: premium-horror-shorts
-    3. **Files:**
-       - Upload this as `app.py`
-       - Create `requirements.txt` (see below)
-    4. **First Run:**
-       - Downloads SDXL (~7GB) - one time only
-       - Subsequent runs: model cached
-    
-    ### Hardware Requirements:
-    
-    - ✅ **GPU A10G (recommended):** 45-50 min per video
-    - ✅ **GPU T4:** 55-60 min per video
-    - ❌ **CPU:** Not recommended (would take 6+ hours)
-    
-    ### 💰 Cost Estimate (HuggingFace):
-    
-    - **GPU T4:** $0.60/hour = ~$0.60 per video
-    - **GPU A10G:** $3.15/hour = ~$2.50 per video
-    
-    Worth it for the quality! 💎
-    
-    ## 🎓 Pro Tips:
-    
-    ### Maximize Virality:
-    1. **Upload timing:** Post at 3 PM EST (peak US engagement)
-    2. **Title format:** "This [object] has a dark secret... 😨 #shorts"
-    3. **Thumbnail:** Use frame from scene 3-4 (peak visual)
-    4. **First comment:** Ask "Did you catch the loop?" (drives rewatches)
-    5. **Hashtags:** #shorts #creepypasta #horror #scary #liminalspaces
-    
-    ### Batch Generation:
-    Run this overnight to generate 5-10 videos, then schedule uploads
-    
-    ### Customization:
-    Edit `PREMIUM_STORIES` array in code to add your own looping narratives
-    
-    ## 📊 Expected Performance:
-    
-    Videos generated with this tool consistently achieve:
-    - 📈 70-85% retention rate (exceptional for Shorts)
-    - 🔄 2.3x average rewatch rate (looping effect)
-    - 💬 High comment engagement ("wait, what?")
-    - 🚀 Algorithm-friendly (watch time + retention)
-    
-    ## ⚠️ Important Notes:
-    
-    - First generation: Allow 60-70 min (includes model download)
-    - Subsequent: 45-55 minutes average
-    - Do NOT interrupt during image generation
-    - GPU memory: ~12GB peak usage
-    - Storage: ~500MB per video output
-    
-    ## 🎨 Quality Comparison:
-    
-    **This Generator vs Others:**
-    - ✅ SDXL (not SD 1.5) = 3x better detail
-    - ✅ 40 steps (not 8-20) = professional smoothness
-    - ✅ 4K downscale (not native 1080p) = crisp edges
-    - ✅ 7-layer audio (not 2-3) = immersive sound
-    - ✅ Professional grading (not basic filters)
-    
-    You're creating **broadcast quality** content. 🎬
+    ## 🚀 Models Used (All Free from Hugging Face):
+    
+    1. **Mistral-7B-Instruct-v0.2** - Story generation
+       - 7 billion parameters
+       - Instruction-tuned for creative writing
+       - Excellent at horror narratives
+    
+    2. **Bark TTS** - Speech synthesis
+       - By Suno AI
+       - Natural prosody and emotion
+       - Multiple voice options
+    
+    3. **Stable Diffusion XL** - Image generation
+       - State-of-the-art image quality
+       - 1024px native resolution
+       - Excellent at atmospheric scenes
+    
+    ## 📦 Requirements:
+    
+    ```
+    gradio
+    torch
+    transformers
+    diffusers
+    accelerate
+    bark
+    scipy
+    pydub
+    opencv-python-headless
+    pillow
+    numpy
+    ```
+    
+    ## 🎯 Best Practices:
+    
+    - Use GPU for reasonable speed (30-40 min)
+    - CPU will work but take 2-3 hours
+    - First run downloads models (~15GB total)
+    - Subsequent runs use cached models
+    
+    ## 💰 Cost:
+    
+    **$0** - Completely free!
+    - All models from Hugging Face
+    - No API keys or subscriptions
+    - Run on free GPU (Google Colab, HF Spaces)
+    
+    ## 🎨 Why This Is Special:
+    
+    Most "AI video generators" use:
+    - Pre-written scripts ❌
+    - Pre-recorded voice ❌
+    - Stock images ❌
+    
+    This uses:
+    - AI-written stories ✅
+    - AI-generated speech ✅
+    - AI-generated images ✅
+    
+    **Every single element created by AI!**
