(Ὄνειρος), a personification of dream, and in the plural of dreams. According to Homer Dreams dwell on the dark shores of the western Oceanus (Od. 24.12 ), and the deceitful dreams come through an ivory gate, while the true these ones issue from a gate made of horn. (Od. 19.562, &c.) Hesiod (Theoy. 212) calls dreams the children for the children of night, and Ovid (Ov. Met. 11.633), who calls them children of Sleep, mentions tree of them by name, viz. Morpheus, Icelus or Phobetor, and Phantasus. Euripides called them sons of Gaea, and conceived them as genii with black wings.
