In your dream, the transformation of the frog into a child, and subsequently into yourself, signifies a profound personal transformation and rebirth. The duck giving birth to a frog and then perishing, while disturbing, represents the end of an old phase or belief system in your life, making way for something new and unexpected. Your nurturing of the frog-turned-girl reflects your self-care and personal development journey.
The fact that the girl is picky about her clothes and needs to blend in hints at your awareness of societal expectations and your desire to fit in, while also maintaining your unique identity. This theme of identity is further emphasized in your other dreams, where you see multiple versions of yourself and a combination of mothers. These dreams suggest an exploration of different aspects of your personality and a search for harmony within yourself.
Overall, these dreams indicate a period of self-discovery, acceptance, and integration of various parts of your personality. It's a positive sign that you're on a path to understanding and embracing the complexity of your identity, leading to a more harmonious and fulfilling life. The recurring motif of spiritual guidance, as symbolized by the highland cow, reinforces that you are moving in the right direction on your personal journey.
