The Arcadia Opera House is described as haunted due to alleged spirits, including a little girl who died in the early 1900s after falling from a window and a woman who was found hanging from the rafters after an affair with the building's owner. Ghost hunters have reported experiencing phenomena like electronic voice phenomena (EVP), moving objects, and unusual occurrences such as a chandelier flashing when not connected to power. The building, which now functions as a museum and antique shop, is a popular site for paranormal investigations. A spirit of a young girl, who died in the early 1900s after falling out of a window, is said to inhabit the building and may communicate through a teddy bear. A woman who had an affair with the original owner is reportedly seen or felt in the building, with stories suggesting she was found hanging from the corner rafters. Another spirit, known as Mr. Creepy, is described as a man who was found in an isolated back room of the building. Ghost hunters and investigators have recorded disembodied spirit voices. Some investigations have captured evidence of objects moving on their own. The building is also noted for having "residual energy," which can manifest as inexplicable events that give people goosebumps. A chandelier in the opera house has been known to flash on its own, even when disconnected from the power source. The historic building, built in 1906, now serves as a museum and a unique antique shop called The Bizarre Bizaar.
