Morpheus

Biography
Morpheus is the Greek God of Dreams, unlike his father Hypnos who is sleep itself, rather than the state of dreaming.

In The Grace Curse
Morpheus appears as a minor antagonist when Chase is aboard the train leading to Washington D.C. Having stopped them from reaching their destination, he and a disgusting mortal named Jayne taunt him and Blake. He reveals himself to be the cause of Chase's nightmares and sends his Oneroi to attack him. Before he can finish him off, Hera appears and forces Morpheus to leave, forcing Jayne to stay behind.
