Dreaming about being pregnant often relates to creativity. The dreamer possibly is craving the time to be creative, or the person is in the process of developing a creative project that manifests itself later.
Though women are more likely to dream about pregnancy than men, both men and women can become or be pregnant in a dream. A woman who dreams about pregnancy, if not seeking a creative outlet, may be working through emotional turmoil or going through a transition period where the dream pregnancy may manifest itself in the real world as the realization of a new self-awareness. A man who dreams about being pregnant may feel as if his virility is being challenged, or the dream may be a sign that he is not being as creative as he would like to be.
