The space was strange and unnerving. Two walls were completely mirrored, reflecting the dim light in eerie patterns. Another wall housed a built-in fan, an electrical panel, and a heavy metal door. Behind that door. He shared his story on Reddit, revealing that he discovered a tiny concrete tunnel just wide enough to crawl through.
The air was damp, heavy, and carried a musty, abandoned scent, as if the basement hadn’t been touched in decades. He didn’t dare venture further, sensing immediately that it wasn’t a place to explore without caution.
“Don’t buy that house, watch Barbarian!” one commenter warns.
“My grandpa built a house in the 1920’s and he built his basement to be a bar during the prohibition era. Maybe?” one more suggests.
