(Greek mythology) the Greek god of sleep; the son of Nyx

In Greek mythology, Hypnos was the personification of sleep; the Roman equivalent was known as Somnus . His twin was Thanatos ("death"); their mother was the goddess Nyx ("night"). His palace was a dark cave where the sun never shines.

Hypnos is the name of a fictional organization from the Digimon Tamers TV series. This covert agency is believed to be named after the title of a minor tale by horror author H. P. Lovecraft and Hypnos the Greek God of Sleep.

Hypnos is an independent record label, located in Portland, Oregon. It was started in 1996 by M. Griffin to release his own recordings, both solo and for his collaborative project, Viridian Sun, and has since expanded into one of the best and well-known ambient-oriented record labels in the U.S. as well as globally.
