Dreams which follow coitus directly are useful in understanding and treating psychosexual disorders. Groddeck's statement, 'It is not true that sexual intercourse is the culmination of erotic life. People are really bored with it', is correct for psychoneurotics who suffer from overt or cryptic sexual maladjustments. The postcoital dreams of such patients are reported, to reveal the immediate factors responsible for lack of sexual satisfaction, and for the resultant moods of irritability and depression. The considerable emotional significance of such dreams is a factor which may be utilized in the interest of psychotherapy. As neurotic conflicts are resolved, alterations in unconscious attitudes may be advantageously observed and clinical progress evaluated in the dream reactions to a standard heterosexual stimulus.
