What are the chances that the Titanic is haunted?

Im told that ghosts get attached if people die suddenly, violently, and if they die without accomplishing important goals they are unwilling to give up. If this is true it would seem that there would be a lot of ghosts on Titanic. Would they be attracted to the wreck, just stuck in the cold and dark on the bottom of the sea? If so, would they know where they are? Would they be haunting the surface where they died? Would they experience the ship the way they remember it/ experienced it?
