If you’re a female, you’ll dream more bad dreams about your mother, than your father. Freud called this the Oedipus Complex. The offspring of one gender, used to be antagonistic (or jealous) towards their parent of the same gender. The child thinks that the parent of the same gender as them, is competing for attention with them, for the parent of the opposite gender. Thus, when the child is male, he will dislike his father, because he thinks father is competing with him, to get the attention of the mother. Likewise, the female child thinks that her mother is competing with her, to get the attention of father.
