Dreaming of cooking, especially in a social setting like a birthday celebration, often symbolizes your desire to nurture and care for others. The act of making pizza together highlights collaboration and the joy of sharing experiences with friends. However, the fact that no one eats the food you’ve prepared may reflect feelings of being overlooked or unappreciated in your social circle. It could suggest that you feel your efforts to connect or contribute are not being acknowledged.

Since you’ve had this dream multiple times, it may indicate a recurring concern or emotion that you need to address in your waking life. Consider whether you feel like your contributions in friendships or social situations are being taken for granted. It might be helpful to communicate with your friends about your feelings or to reflect on how you can foster deeper connections with them.

Overall, these dreams could encourage you to find ways to ensure you feel valued and recognized in your relationships. Remember, it's also essential to take care of yourself and ensure that your needs are being met in your social interactions.
