The God ''Hypnos'' was the personification of One's ''ability'' to attain Sleep. It was because of Hypnos Mankind could ''dream'' and rest''. Lack of proper respect (worship) to Hypnos would earn one lack of sleep and nightmares (which, as We have seen – had their own ''Demons''). Brother to The God of Death, whose Father and Mother was ''Night and Darkness'' (all things relating to Sleep). For the most part shown as a ''Young Man'' – Hypnos was seen as a ''kind and gentle'' Entity.
