I was at my nana’s home and when I looked out the window I saw my recent ex with somebody else in a car with tinted windows
This dream could indicate that you are feeling insecure and worried about your recent breakup. Seeing your ex with someone else in a car with tinted windows could symbolize that you feel like you are unable to see what is happening in your ex's life and that you are feeling left out or excluded from their life. This dream may also suggest that you have not fully processed your breakup and that you still have emotional ties to your ex that need to be resolved. It may be helpful to take time to reflect on your feelings and work through any unresolved emotions surrounding your past relationship.
