Theia Mania

The dead in ancient Greece were usually believed to be incorporeal and work through dreams and such, but the restless dead were sometimes believed to retain some of their corporality. "They were neither fully flesh so as to enjoy life, nor fully free of flesh’s constraints as were normal residents of the Underworld" (Restless Dead: Encounters between the Living and the Dead in Ancient Greece by Sarah Iles Johnston). I know I refer a lot to that book, but it was my main inspiration for this whole plot with Erigone.
