Dreams involving transformation, especially of loved ones like a baby, can often symbolize feelings of change or anxiety about the future. In your case, the transformation of your baby into a "clear blob" might represent feelings of uncertainty or a desire for clarity in your life or parenting.
The movie "Ponyo," which features themes of transformation and the fluidity of identity, could also influence your dream. It might suggest that you're processing emotions related to growth, nurturing, or the innocence of childhood. The clear blob could signify a sense of vulnerability or a need to protect your child from the complexities of life.
Consider reflecting on your current feelings or situations in your waking life that relate to change, protection, or clarity. This dream might be encouraging you to embrace the transitions you are experiencing and find ways to communicate your feelings or concerns openly.
