In order to encourage a pattern shift in an uncertain session situation, I can offer my client a projection surface. Then I give her the tip to let a messenger appear who should give her a hint.
To support the imagination, I play the sound of footsteps. The messenger, who comes acoustically from “outside”, usually brings a message. The implementation of the message brings the client back into action and thereby drives the process forward. According to the law of symmetry breaking, every client develops a different idea about the origin of the footsteps. One hears his father or brother coming towards him, another his boss, a fourth a policeman.
