The door in the basement

Hi my name is Jack. I moved into a new house last week and when I was exploring the basement of my new house I discovered a door. But it wasn’t any normal door. It looked more like a stone brick wall but it had a door knob on it so that gave it away. I wondered what was behind the door, a secret spy base? Has someone been living in this house. Maybe that’s why the last family moved out. I was confused. But for some reason I decided to open the door. What I saw in that room was unspeakable.
