in Greco-Roman mythology, one of the sons of Hypnos (Somnus), the god of sleep. Morpheus sends human shapes (Greek morphai) of all kinds to the dreamer, while his brothers Phobetor (or Icelus) and Phantasus send the forms of animals and inanimate things, respectively. It is possible, although not very probable, that his name actually meant Dark (from Greek morphnos).
