A person dies when he loses the ability to dream, and the dream game is an invitation to cling to dreams in times of nightmares.

The story of a soul trying to cling to its right to release its last dream despite the resistance of the train of life. When the train leaves without that, the grip of the body relaxes, so the bird of the last dream sets off to carry the soul between the human world at times and the animal world at other times. In each cycle, that soul struggles with the obstacles of reality, and is victorious at times and defeated at other times. But she clings to her right to unleash her last dream.
