Transference originates in the client. It exists or it doesn't because it stems from unmet needs in childhood. A competent therapist cannot "implant" a transference in a client. There are, of course, incompetent/unethical therapists who inflict all sorts of harm. But to call such experiences "transference" is both inaccurate and misleading.
If a client is engaging in therapy, and the process of that therapy results in persistent feelings of desperation, self harm, life altering obsessiveness, etc--worse than before therapy-- then that's either bad therapy, or inappropriate therapy for that client at that time. Transference has nothing to do with it.
