Ontological-Hysteric Theater is a form of performance art that explores the nature of existence and reality. It often blurs the lines between fiction and reality, inviting audiences to question their perceptions. This style emphasizes the emotional and psychological experiences of characters, creating a sense of intimacy and immediacy. The term is associated with the work of Richard Foreman, a prominent figure in avant-garde theater. His productions often feature fragmented narratives and unconventional staging, challenging traditional storytelling methods. This approach encourages viewers to engage actively with the performance, fostering a deeper understanding of the themes presented.
