Dreams involving car accidents, especially those involving loved ones, can be quite distressing. They often symbolize a loss of control or feelings of anxiety regarding your relationships or responsibilities.
In your dream, the car represents your life journey, with your mom driving potentially symbolizing her influence or role in your life. The hydroplaning and spinning could signify a situation where you feel overwhelmed or uncertain. The tragic outcome of your mom dying may reflect fears of loss or change in your relationship with her or an anxiety about her well-being.
This dream could also indicate underlying feelings about independence, growing up, or the fear of change. Consider reflecting on your current relationship with your mom and any stressors in your life that may be contributing to these feelings.
It might be helpful to talk to someone about these feelings or reflect on ways to regain a sense of control in your life. Remember, dreams often serve as a mirror to our subconscious, helping us to process our emotions and experiences.
