The Locked Box is the fear of tight enclosed spaces, and helplessness. Some theorize it also serves as the Fear of being betrayed. It manifests as a large wooden box wrapped in chains and a padlock, with its key laying right in front of it. It lures its victims in by their own curiosity, and those who attempt to open the box instead find themselves pulled in and locked within it. The key is then left again as bait for its next victim as the inside of the box constantly shrinks smaller and smaller until the victim trapped inside has no room to move even a single muscle.
