What is thought projection and transference?

Projection:

Thoughts of infidelity to a partner may be unconsciously projected in self-defence on to the partner in question, so that the guilt attached to the thoughts can be repudiated or turned to blame instead, in a process linked to denial.[13]

Projection of a severe conscience[14] is another form of defence, one which may be linked to the making of false accusations, personal or political.[15] Alternatively, a bully may project his/her own feelings of vulnerability onto their victim,[16] or a patient their feelings of hope on to the therapist.[17]
