Is The Queen Mary haunted?
United States Reported haunting level 5 of 5

What actually happened
During the Second World War the liner was converted to a troopship and carried 810,000 military personnel before returning to civilian service.
The history
Built in Scotland from 1930, the Queen Mary made her maiden voyage from Southampton on 27 May 1936 and carried 2.2 million peacetime passengers before retiring to Long Beach in 1967.
What people report
The ship's own tours tell of Jackie, a giggling child said to haunt the first-class pool, and of resident spirits in the hotel staterooms.
That paragraph is reported tradition, not a claim about what is there. The history above it is sourced; the stories are recorded because people tell them.
