ovid called morpheus and his brothers, the other sons of somnus, the "somnia" ("dream shapes"), saying that they appear in dreams "mimicking many forms". ovid gives names to two more of these sons of sleep. one called icelos ('like'), by the gods, but phobetor ('frightener') by men, "takes the form of beast or bird or the long serpent", and phantasos ('fantasy'), who "puts on deceptive shapes of earth, rocks, water, trees, all lifeless things".
