Ghost Light Masquerade is San Diego’s ultimate Halloween performance experience — where the boundary between theatre and the supernatural is nothing more than a curtain. Step Into the Legend. When the theatre goes dark, a single lamp remains: the ghost light. Practical tradition says it wards off accidents. Old superstition says it keeps spirits away. But what if it doesn’t keep them out? What if it beckons them in? For a limited time each October, The Nocturne Theatre descends and conjures an immersive, otherworldly masquerade where superstition walks, legends breathe, and Spirits dance. Ghost Light Masquerade unravels a spectral theatre that exists only for those who dare to enter.
