Werewolves' minds work a little differently in my dreams. They can turn into wolves at will and are forced to turn every Full Moon. When they turn on any moon that isn't full they go a little crazy, lose a little self-control. Eventually they become what we call a vargulf. It's a werewolf that kills for sport and doesn't eat its prey. After a while the vargulf stops shifting back into human form. It's trapped.
