In psychoanalysis, transference refers to a situation when the patients see the therapists as a source of emotional hollows that they've been craving for in their life.
This tend to occurs because for most patients, their therapists would be the only person that they perceived as someone that can understand them. This is what cause the extreme jealousy when such patients know their therapists spends time with other patients.
