Dreams involving past relationships, particularly those tied to deep emotions, can often reflect unresolved feelings or concerns about those connections. In your dream, the text from someone who loved you suggests a call for help or support, which could symbolize your own desire to assist or revisit past emotional ties.

The legless woman holding a baby is a striking image that may represent loss or the fragility of life. The fact that she has no legs could symbolize feelings of inadequacy or the inability to move forward, perhaps reflecting the emotions surrounding the passing of the person's mother. The baby transforming into a cat might signify transformation or independence, as cats often symbolize self-sufficiency and mystery. This transformation could be indicative of how you perceive change in your life or in the lives of those around you.

Seeing the woman chase you while now having legs suggests that the feelings or memories associated with this past relationship or loss are still present and could be pursuing you in your waking life. The act of driving away with friends may indicate a desire to escape from these emotions or memories, showing a need to protect yourself from past pain.

Overall, this dream seems to point towards themes of loss, transformation, and the complexities of past relationships. It may be beneficial for you to reflect on your feelings about this person and their loss, as well as how it affects your current emotional state. Consider reaching out to your friend to offer support or to discuss the feelings that this dream may have brought up for you.
