The Authors discuss the Squiggle-game, a tecnique created by Donald Winnicot, that they often use in their clinical practice to promote change in people. This tecnique realize the attunement of the therapist to the needs of the client realizing an empathic and cooperative relationship in which the client himself will be able to use his own resources to activate a self healing process, for solving all those difficulties that hang over in some particular moment of life. The Squiggle is, in fact, an instrument and a place to build the Rapport in which the client can interferes on his Map or Script and by activating the unconscious creativity, he can create lines and drowings that become, then, metaphor of Self, in which the old and the new interweave, forming a new Reference Frame. The Authors go back to the important contributions of the Ericksonian Naturalistic Hypnosis and connect them to other important theories (the Attunement of Winnicot, the alpha function of Bion, the mirror neurons of Rizzolatti and Gallese, the emotionalaffective regulation and self- regulation of Shore). At the end the Authors present a clinical case to explain the theories and to show how, building a shared place, the client can elaborate a metaphor that become expression and evolution of the Self.
