<psychoanalysis> freudian mechanism by which unacceptable wishes and thoughts are banished from conscious awareness but continue to unconsciously and, thence, find expression in dreams and slips of the tongue, and sometimes in compulsive behavior, obsessive thoughts, and other forms of psychopathology.
