Thirteenth Floor Entertainment Group, the producers of world-class live events and location-based entertainment experiences, today announced the highly anticipated return of one of LA’s most popular interactive events, Delusion. Officially open to the public on Thursday, September 15th, Thirteenth Floor and Director Jon Braver will once again bring his one-of-a-kind interactive horror theater series to life in the historic Phillips Estate with a new play titled Delusion: Valley of Hollows. Delving into an era never before explored in an interactive theater, the play will explore 1970’s American cults, with a supernatural twist.
