Oneiroscopy is the art of divining sympathetic dreams within the Skein in order to travel through them - usually using divining methods that involve luck or chance. The changeling selects a particular dreamer as the subject of inquiry and a target dream within the myriads of the Skein as her ultimate destination. Normal humans work best; for some reason their life-threads easily link to others. Supernatural beings are less bound to the whole Skein, but powerfully linked to select threads as they lead wonderful, terrible lives.
The Autumn Court traffics the most with Oneiroscopes and is willing to teach members the way to use them.
