Users are the physical form of nightmares and bad dreams and can control them to their will. In the real world the user may have very little power but in the dream world the user has near limitless power, they can turn any dream into a nightmare and torture their victim with it. Users gain power by causing nightmares but some may kill their victim and absorb their soul to increase their power further. If the users body is destroyed they can live on in dreams and possibly possess another persons body while they sleep and eventually take full control of them.
