Lemming.

Yukichi Matsumoto's 2013 stage adaptation of Shuji Terayama's "Lemmings". Two cooks share a room, one of which talks with his mother's head: it lives beneath their tatami mats. On the other side of their room's wall, lives a wife who desperately cares for her feverish husband. As more and more walls are tore down movie studios, hospitals and prisons are revealed, destroying the physical boundaries between their boarding house and the city.
