A slow watch:
late 14c., name for the god of dreams in Ovid, son of Sleep, literally “the maker of shapes,” from Greek morphē “form, shape, figure,” especially “a fine figure, a beautiful form; beauty, fashion, outward appearance,” a word of uncertain etymology. Related: Morphean. Morphō was an epithet of Aphrodite at Sparta, literally “shapely.”
… Morpheus was one of the minor gods of Greek mythology, a very mysterious character who dwells in the shady Realm of Dreams, where he works sending the messages of the gods, and creating dreams.
