This dream appears to be rich with symbolism and may reflect various aspects of your life and emotional state. Here are some interpretations of the key elements:

1. Rescue Theme: Your friend's request for rescue may symbolize feelings of responsibility or a desire to help those close to you. It could also reflect your own need for support or assistance in your life.
2. Legless Woman: The woman without legs could represent someone who feels powerless or restricted. This might symbolize a part of yourself or someone in your life who is struggling. Her transformation into a woman with legs at the end may suggest a shift from helplessness to empowerment, possibly indicating a change or growth in your own life or in a relationship.
3. Baby to Cat Transformation: The baby represents innocence, vulnerability, or a new beginning. When it transforms into a cat, it may signify independence or a shift from responsibility to freedom. Cats often symbolize intuition and mystery, hinting that you may need to trust your instincts in a situation.
4. Escape Car: The act of escaping may indicate a desire to flee from a situation or emotional burden. This could be a reflection of anxiety or stress in your waking life that you wish to avoid.
5. Chasing Woman: The woman chasing you, especially after gaining legs, might symbolize unresolved issues or fears that you thought you had escaped but that are still following you.

Overall, your dream suggests themes of support, transformation, and the interplay between vulnerability and empowerment. It may be helpful to reflect on your current relationships and any feelings of obligation, as well as how you cope with challenges. Consider what aspects of your life you feel the need to "rescue" or escape from, and think about how you can address those feelings constructively.
