Dreams involving deceased loved ones, especially a parent, can be quite powerful and emotionally charged. In your dream, the presence of your mother suggests a deep connection and perhaps unresolved feelings regarding her passing. The setting of your auntie's house may symbolize family ties or a place of comfort, while the car represents a transition or journey in your life.

Your mother's calm demeanor and her reassurance that "don't worry about it" might indicate that she wants you to find peace with her absence. This could reflect a desire for you to move forward without holding onto grief or worry about what others think or feel regarding her passing.

Overall, this dream might be encouraging you to embrace the memories of your mother while also recognizing that life continues. It could be a gentle reminder to focus on your own path and well-being, knowing that she is still a part of you in spirit.

If this dream resonates deeply with you, consider taking some time to reflect on your feelings about her passing and how you can honor her memory while also caring for yourself.
