Magnum, P.I. (1980)

Thomas is running an errand to a local museum for Higgins' upcoming pageant for the Anglo-Hawaiian Historical Society, when he catches sight of a woman attending a funeral who, he soon learns, resembles a beautiful Hawaiian princess who tragically died in a fire in 1910. Thomas becomes enamoured with the elusive beauty, and experiences visions of himself, in 1900s naval uniform, with the woman. The mystery grows even more when he receives a package in the mail containing such a naval uniform, and a locket holding photographs of what looks like himself and the princess... Is Magnum once again experiencing something ethereal, or is somebody using the story of the princess to their advantage?...
