Morpheus (mythology)

Morpheus (Greek: Μορφέας, Μορφεύς, "he who forms, shapes, moulds", from the Greek morphe) is the Greek god of dream.
Morpheus has the ability to take any human's form and appear in dreams. He is the son or brother of Hypnos, the god of sleep. Nyx (the goddess of night) is his mother/grandmother. The brothers (according to Hesiod) or sons (according to Ovid) of Hypnos — the Oneiroi — are rulers of visions, and include Phobetor (also known as Icelus), and Phantasos.
Morpheus is spoken of in the Metamorphoses of Ovid. It is also believed that in the Iliad he is spoken of as "Dream." He is also referred to in Edmund Spenser's The Faerie Queene (1590). He sleeps on an ebony bed in a dimly lit cave, surrounded by poppy flowers. According to Ovid, Morpheus concentrated on the human elements of dreams, his brothers Phobetor and Phantasos being responsible for animals and inanimate objects, respectively.
Morpheus sends images of humans in dreams or visions, and is responsible for shaping dreams, or giving shape to the beings that inhabit dreams. Phobetor made fearsome dreams (etymologically related to "phobia" from the Greek φόβος "fear"). Phantasos produced tricky and unreal dreams (hence "fantasy", "phantasmagoria", etc.). Together these attendants of Hypnos rule the realm of dreams. Morpheus also had special responsibility for the dreams of kings and heroes. For these reasons Morpheus is often referred to as "Morpheus the Greek god of dreams" in superiority to his brothers.
The drug morphine (once "morphium") derives its name from Morpheus based on its dream-inducing power.
