Davy Jones's Locker is a metaphor for the bottom of the sea: the state of death among drowned sailors and shipwrecks. It is used as a euphemism for drowning or shipwrecks in which the sailors' and ships' remains are consigned to the depths of the ocean (to be sent to Davy Jones' Locker).The origins of the name of Davy Jones, the sailors' devil, are unclear, with a 19th-century dictionary tracing Davy Jones to a "ghost of Jonah". Other explanations of this nautical superstition have been put forth, including an incompetent sailor or a pub owner who kidnapped sailors.
The draugr or draug (Old Norse: draugr, plural draugar; modern Icelandic: draugur, Faroese: dreygur and Danish, Swedish, and Norwegian: draug) is an undead creature from the Scandinavian saga literature and folktale.
Commentators extend the term draugr to the undead in medieval literature, even if it is never explicitly referred to as that in the text, and designated them rather as a haugbúi ("barrow-dweller") or an aptrganga, literally "again-walker" (Icelandic: afturganga).
