The Buveur de Reve was an idea that I have long held in my mind. A creature capable of consuming and subsisting off of the stuff of dreams. It would then make sense for the person to have dreamless sleep, given that the dream was siphoned away. I likened it more to a fae type creature here, mostly to loosely tie into the themes I’m running, but in my own personal lore they are more like that of a succubus or night hag. Terrifying and oddly alluring.
