The USS Olympia is reportedly haunted by spirits and phenomena, including apparitions of a translucent man, disembodied voices, and unexplained sounds. Visitors and paranormal investigators have documented full-body apparitions, and electronic voice phenomena (EVP) such as a voice saying, "I think I'm in love" have been recorded. The ship's long history, with many deaths and a reputation for being "hoodooed," contributes to these stories of a haunted maritime landmark. Some visitors and investigators have seen apparitions, including a full-body manifestation in the engine room that vanished, and a translucent form of a man appearing elsewhere on the ship. Investigators have detected electronic voices on recordings, such as one saying, "I think I'm in love," potentially capturing spiritual communication. Other experiences include unexplained sounds, smells, and a general sense of unease reported by some guests.
