Sexual dreams in adults are not as common as most believe and typically symbolize inner conflict. For men, dreaming of having sex with a daughter symbolically expresses a fear of secret sexual desires or problems relating to adult women. For a man to dream of incest with his mother may represent the desire he had for her as a little boy during his development. Freud termed this the Oedipus complex, occurring as a normal part of psychosexual development(phallic stage). At approximately the age of five and a half years, boys begin to identify with their fathers and likewise desired their mothers. In girls, Freud called this the Electra complex.
Dreaming of incest with brothers or sisters may symbolize a merging of the masculine and feminine aspects of the dreamer. Carl Jung termed these aspects the anima (female) and animus (male). He believed that we all have opposite gender aspects within our personalities and that to recognize and accept this promotes mental and emotional balance.
