Sandman

The Sandman is a mythical character originating in Germanic and Scandinavian folklore who puts people to sleep by sprinkling magical sand onto their eyes. In traditional folklore, the Sandman is said to sprinkle sand or dust on or into the eyes of children at night to bring on sleep and dreams, with the supposed result being the grit or "sleep" (rheum) in one's eyes upon waking. The character has been featured in literature, such as E.T.A. Hoffmann's 1816 short story Der Sandmann, and has appeared in various forms of media, including children's television shows like Unser Sandmännchen and Bonne nuit les petits. The character's name and role have varied across cultures, with names such as Ole Lukøje, John Blund, Jon Blund, and Klaas Vaak.learn more on wikipedia
