Esquizo (1970)

Esquizo takes place in a psychiatric hospital. A mental patient (Serena Vergano) is escorted into an operating room, where electrodes are attached to her scalp. The doctors dissect his brain and we enter the brain with a loud, jarring cry. In this space detached from reality, a group of actors perform elaborate interpretive dances. They jump, land on top of each other, place their hands on their bodies and form various shapes.

Unfortunately the movie Esquizo is not yet available on HBO Max.
