We have presented some preliminary findings from a survey on countertransference dreams (CTDs) sent out to all members and candidates of the Canadian Psychoanalytic Society. Despite the limitations of the survey, which of necessity focused largely on the manifest content of the analysts' reported dreams, we have gathered considerable evidence to draw the following conclusions. CTDs are common, whether one is a candidate or an experienced analyst. In addition, our findings support the concept of a resonance between the patient's and the analyst's unconscious at all stages of analytic work. CTDs may signal this resonance in all of its affective intensity and conflicted nature. Of particular interest is the evidence afforded by the survey that there are significant differences in the manifest content of CTDs reported by male and female analysts. Some possible unconscious dynamics underlying this observed difference, which was an unexpected finding, are discussed.
