The Dreamwalkers (Marcheurs de rêves)

Description en anglais

You are on a mission for the order of the Dreamwalkers, an order as ancient as human being's ability to dream. These lucid dreamers have an oath to protect the dream world and ours from the denizens of the nightmares that try to plunge humans into tormented and eternal sleep. Now three of them are holding a child in his own nightmares and spreading chaos. Wake him up before it's too late.
