First 100 Days Inside a Hidden Concrete Bunker as the Outbreak Spread Across the Region

title: First 100 Days Inside a Hidden Concrete Bunker as the Outbreak Spread Across the Region 🧱 Story Summary: The first days of the zombie outbreak were chaos. The first weeks were silence. But the real test began after that. I sealed myself inside a hidden concrete bunker before everything fully collapsed — no windows, no outside contact, just reinforced walls and whatever supplies I had managed to store. Days blurred together. Then weeks. Then months. In this fictional creepypasta survival story, a survivor endures the first 100 days of the zombie outbreak inside a sealed underground bunker, where survival isn’t just about staying alive — it’s about holding onto reality. With no updates from the outside world, every sound becomes a threat. Air systems echo louder than they should. Footsteps seem to travel through solid concrete. And somewhere around day 70… something begins making noise above the bunker that doesn’t stop. Because surviving 100 days underground isn’t the hardest part. It’s what’s still there when you finally start counting the days.
