Dreaming Nightmares

Autumn and Coco both have the ability to get inside of people's heads. They are capable of invading another person's dreams whilst they are sleeping and of course alter the way that the dreams play out.
Coco uses this power for evil and does all that she can to torment, torture and worry people whilst they dream.
Autumn is the good force that does everything that she can to try and stop Coco from hurting people.
Who will triumph? Good or evil?
