Dreams about pregnancy and childbirth can carry significant symbolism and often reflect your feelings about new beginnings, creativity, or personal growth. In your dream, being pregnant might indicate that you are nurturing a new idea or project in your waking life, something that is developing within you and requires attention.

The experience of giving birth, especially in a painful but quick manner, could symbolize the challenges you face when bringing this idea to fruition. Pain often represents the struggles and sacrifices that accompany significant changes or new responsibilities. The overwhelming presence of your family may suggest that you feel pressure from external expectations or support, which can be both helpful and burdensome.

Your boyfriend's absence during the birth and his later arrival may represent feelings of disappointment or concern regarding his support in your life. This could reflect a fear of being alone in your endeavors or a desire for a more active partnership. His choice to smoke weed could symbolize avoidance or distraction from responsibilities.

Overall, this dream may be pointing to your feelings about upcoming changes, your support system, and your need for acknowledgment and partnership during challenging times. Consider reflecting on these themes in your waking life to gain deeper insights into your current situation or relationships.
