Narrative Writing: Unlocked Door

I was in an empty hallway except for a couple of old dusty pictures that were nailed crookedly on the wall. At the end was a big wooden door with weird carvings on it.

Inside was a big room with old tables and chairs. I walked into the next to room and saw that it was empty but there was a door at the other side of the room. My footsteps echoed as I walked across the room and opened the door. There was an empty hallway except for some dusty pictures on the walls.

I tried to open it again and pushed hard and it slowly opened just a crack. A faint yellow light illuminated from the crack. The worn doorknob was icy cold to the touch as I held onto it and gently pushed the door farther open...
