Dreaming about having a baby can symbolize new beginnings, creativity, or the birth of new ideas. Since you and your boyfriend are involved in this dream, it may reflect your feelings about your relationship and potential future together. Not knowing the gender of the baby could indicate uncertainty or anticipation about what the future holds for you both.
This dream might be encouraging you to explore your thoughts and feelings about commitment, family, or your aspirations as a couple. Consider what aspects of your life might feel like they are starting anew or what you might want to nurture and develop. It could also be a sign to communicate openly with your boyfriend about your hopes and dreams for your relationship.
