This particular scenario starts with patient finding themselves in an elevator, leading into an office. The environment consists of rooms and corridors connected to each other in a way that leaves no accessible way out. There are no windows or any other emergency exits available and the patient must go through corridors that get narrow as they move forward. After the patient enters the reception room, there will be a long corridor ahead of them. These corridors will get smaller and less bright as they go through them. There will be a restroom and a storeroom along the way of these corridors to increase the similarity to enclosed spaces seen by the patient in real life. In the end of these corridors, there are rooms with dynamic walls. After the patient enters this room, the door will be locked and they cannot leave. Walls can be moved by the therapist to stimulate fears of enclosed space in patients. Therapist has full control over the movement of the walls towards each other.
