The Queen Mary has had its fair share of ghosts and tragic deaths (49 to be exact).  She was called the Grey Ghost during her years as a World War II transport ship, and many people who have worked on or visited the old luxury ocean liner report seeing things that fall well into the lines of a haunting.  The Queen Mary has since however been turned into a Hotel when it was purchased by the city of Long Beach, California in 1967.  There are accounts of people seeing a "lady in white" around the front desk area of the hotel, and furniture moving by itself. One of the most haunted areas is the engine room of the ship where a young sailor was crushed trying to escape a fire.  Many people report knocking and banging noises on pipes around the door.  The ghosts of children have been said to haunt the pool/changing room areas, and in the front hull of the ship, a spirit can be heard screaming sometimes.  You can also take tours of this interesting place.  http://www.queenmary.com/
