Oneiromancy
They wish to sleep, Dreamers afraid of the wake.
They studied the Dream for so long it started to look like the images living in their sleepless nights. Sure to find there something to give them purpose, they gave their all to the crows. With eyes as payment, the birds sing.
Oneiromancy is the name give to the manipulation of the mind, through sleep, suggestion and illusions. It lets an Artist create shapes and sounds in the mind or a given individual, read their thoughts or give them orders in the forms of alluring suggestions.
