The clinical situation experienced during a therapeutic workshop for children allows us here to problematize the approach to the manifestation of unshaped affects in the psychoanalytical setting. The child psychoanalysis, which confronts us to the violence and the chaos of the drives and to the processes through which they organize around an object, helps us understand the vectorization of the drives in the relationship to the other (maternal, transferential). The role of the phantasm, in the child as in the analyst who lets himself play and be surprised, opens up new forms of representation of ourselves, of the other, of the world. The function of surprise and of the unknown seems, thus, fundamental in this work in which the phantasm is organized in the discontinuity that is usually established between the real and our construction of an imaginary continuity of ourselves. This clinical experience with children allows us to finally establish some necessary elements in the psychoanalysis of adults in which the problem of shapelessness seem to organize the transferential relationship. The work of a choreographer and a minimalist musician allows us to further understand the role of the phantasm in the analyst, in his/her approach to the archaic manifestations of affects that cannot be manifested, except through an act, shapelessly.
