Melinoe

In Greek mythology, Melinoe is the goddess of ghosts and nightmares. It is said that she grants madness to those she haunts. She is the daughter of Persephone and Hades. She lives in the Underworld. She has a pale complexion and a short temper and takes after her father in almost every way, except from her beauty that she gets from her mother Persephone. Melinoe has the powers to turn any mortal insane by her phantoms.

Melinoe is often depicted as a shadowy, ghost-like figure often with the ability to shape-shift and take on various forms. She is said to be able to haunt the living and cause them to experience disturbing dreams and visions, making her a powerful figure in the realm of the supernatural

Little is known about Melinoe, but ancient Greeks used to conduct rituals and acts of praises to her as a sign of devotion and to garner protection from ghosts.
