According to Carl Gustav Jung, incest symbolizes the desire for union with the essence of oneself. This is why some gods of ancient mythologies were conceived in this way. In any case, this dream is very uncommon. In oneiric terms, incest can indicate various things. The most normal is that it reminds you of the dependence you have on your mother, as well as the fear you have at the idea of separating from her. All this reveals immaturity and an inability to make decisions. It may also remind us, as Jung claimed, of our origin and the strong desire to return to it, recover our identity, and be reborn. Incest with a brother or sister represents the union of your feminine and masculine sides. (See sex ) In ancient times, this was so taboo that no books about dreams make any reference to it.
