Update: Since this article posted, Delusion's Facebook page has announced the close of its season, and the ticket-purchasing option on the official website has been removed.
Though the show is officially sold out and no new dates are listed on the official website, Delusion Lies Within recently put out a casting call on its Facebook page, seeking cast members for performances on November 20-23 and December 4-7, 11-14. The last time a date was officially added, the performances sold out within hours. If you do not want to miss further opportunities to experience this interactive-theatrical haunted house, you should sign up on their website for email announcements; then purchase tickets as soon as they become available.
Delusion Lies Within is performed in a real house at 2525 Arlington Avenue, Los Angeles, CA, 90018. Tickets (when available) are $60.
