Hello Beckie,
In your dream about baking a cake on a TV show, this scenario could symbolize a desire for recognition and achievement in your waking life. The act of baking, a creative and nurturing activity, may represent a part of you that's yearning to express itself and be appreciated by others. Being on TV suggests that you want your talents and efforts to be seen and validated on a larger stage, possibly hinting at some unmet aspirations or a need to be acknowledged in your personal or professional life.
Reflecting on your previous dreams involving themes of regression and care, such as wearing a diaper and the associated feelings of comfort and then sadness, it seems there's a contrast between a desire for independence and competence, as shown in your latest dream, and a longing for care or simpler times. Both themes touch upon a need for understanding and support, which might be lacking or desired in your current situation. The feelings of sadness when waking up could relate to a sense of loss or unfulfillment that might be present in your life right now.
If you find these themes recurring and they resonate with your feelings or experiences, it may be beneficial to explore these aspects further. Your dreams are a reflection of your inner world, and they seem to be expressing a rich tapestry of emotions and desires that are worth acknowledging and understanding.
