One-Way Entrance

"And consider this dismaying observation: this chamber has no windows, and no doors. Which offers you this chilling challenge: to find a way out"

- Haunted Mansion ride

If the protagonists go into a haunted building, there is a non-zero chance that while their back is turned the walls and doors will turn into hole-less walls, leaving the unfortunate protagonists trapped inside. A less supernatural variant is for the doors to slam shut behind them and refuse to open.
