The Queen Mary was launched in 1934 and now permanently docked in Long Beach, California, as a floating hotel and historic attraction, the world's most haunted cruise ship? Maybe!

The tour features reenactments of historic events and paranormal activity that has been reported over the years by staff -- and visitors. So what exactly is going on onboard? Reports of haunted happenings include:

The eerie cry of an infant in the third-class children's playroom
A young woman in an evening gown dancing alone in the Queen's Salon
Ladies in vintage bathing suits wandering around the first-class swimming pool
Wet footprints, also at the pool -- even though it's completely empty

As a passenger vessel, the Queen Mary completed 1,001 Atlantic crossings before retiring in 1967. It also served in World War II from 1940 to 1946, carrying a total of 765,429 military personnel. Fifty people reportedly died onboard over the years, and it is said some still remain (including one crewmember allegedly crushed to death accidentally during a drill involving a watertight door).

The guys from the popular SyFy series, "Ghost Hunters," have investigated reports of paranormal activity aboard the Queen Mary as well as in an exhibit of Titanic artifacts.
