A member of The Dream include any people who live between dimensions and subsist on the essence of dreams of others. The name of their parallel world is simply The Plane of Dreams.... More, these beautiful creatures resemble water spirits. They have control over water, and – like all members of the Dream – feed off human dreams in sleep. (Don’t worry. That part benefits us.) Closely related to both Dryads and Sylphs.
If you meet one, you don’t have much to worry about. They’re barely part of this world, and communicating with one is a little like trying to be heard from the depths of a pond.
