The dissociative process is the physiological movement of the infinite configurations of the Self. Traumatic events can block its movement and then only a few, recurrent, traumatic configurations prevail preventing the physiological "collision of subjectivity". In the movie an awkward and, at the same time, wounded teacher, moves the block of the dissociative process of the class and - through the class - also his own block. What gives life to the dissociative process is Lazhar’s contact with ancient and warm configurations of his life and, the class, finally, can recognise that they’ve suffered, but, nevertheless, surviving to a severe violence.
