To provide an experience system that makes a person experience an strange surprise.

This is an experience system 1 that gives a person P an experience. This experience system 1 comprises a plurality of rooms 3a, 3b, 3c separated by a wall 2, at least one entrance 4a, 4b, 4c built between above-mentioned rooms, and a movable wall 5 that moves crossing in front of the entrances 4a and 4c. The person P will experience an appropriate dramatic presentation in the room 3b, by moving from the room 3a to the room 3b. While the person P experiences it, the movable wall 5 moves in the direction of an arrow A, and the entrance 4b moves to the entrance 4c of the room 3c. Although the person P intends to return to the room 3a he/she has left at first, he/she returns to another room 3c, so that he/she will have a strange experience.
