Morpheus (Greek: Μορφεύς, Morpheus, or Μορφέας, Morpheas, “shaper [of dreams]”) in Greek mythology is the God of Dreams, leader of the Oneiroi. He has the ability to take any human form and appear in dreams. According to Hesoid, Morpheus is the son of Nyx, the primordial goddess of the Night, produced parthenogenically, or as Cicero claims, with Erebus, the embodiment of Darkness. He is the oldest of triplets known as the Oneiroi, along with Icelus and Phantasos. For this reason, he is also referred to as Oneiros. The Oneiroi are attendants of Hypnos, the God of Sleep, bringing dreams to the mortals and gods who fall under the power of Sleep.
