Dreams about driving often symbolize your journey in life and the direction you are taking. In your dream, driving with your ex-girlfriend and feeling cozy and happy suggests a sense of nostalgia and perhaps unresolved feelings from that relationship. The sunlight shining through the window may represent clarity and positivity in your life, but it also caused you to temporarily lose visibility, indicating that sometimes, emotions can cloud your judgment or perspective.
Asking her to take the wheel could signify a desire to relinquish control or let someone else guide you through certain situations in your life. The fact that you didn’t find anything at the shops may indicate a feeling of searching for something that is currently elusive or unfulfilled in your waking life.
Overall, this dream might reflect your current emotional state regarding past relationships and your search for direction or fulfillment. Consider what aspects of your past relationship you miss and how they relate to your current life circumstances. It could be beneficial to reflect on what you truly want moving forward.
