The two vignettes from the literature presented in this chapter, as well as the vignette to be presented in the next chapter, illustrate how the enacted dimension constitutes a continuous, unconscious backdrop to the day-today work of analysis. Within this second dimension of the treatment process, without the awareness or intent of either party, preverbal and nonverbal experience fi nd shape and expression. The vignettes illustrate how this in vivo treatment version of the early relationships and events that shaped the patient’s personality offers the potential for previously unformulated experience to be reintegrated into the fabric of the patient’s internal world and external life.
