Today, irrationality is no longer confined to the patient's symptomatic manifestations; it is also present in the manifestations of the analyst's countertransference during sessions, the most unusual and strange marks of which are found in the hallucinatory tendency of the drive, or in the “work of figuration” (Botella). Through what could be considered as an effect of the “taming” (Freud) by the psychoanalyst of the drive impulses at work in the unrepresented or poorly translated traces projected by the patient, the work of figuration defuses the “work of the negative” (Green) in the latter, within a contemporary psychoanalytic process known as “transformational”. Irrational countertransference phenomena may be seen as an aid to understanding and thinking about, in the Bionian sense of the term, the irrationality of the patient's psyche, thus promoting a process of transformation of the unrepresentable.
