Dreams about driving often relate to your sense of control in life and the direction you're taking. In your dream, realizing you were going the wrong way suggests a feeling of uncertainty or a concern that you may be making poor choices in your waking life.

The transition from the highway to a bridge over water could signify a journey or transition phase, but the fact that the bridge ended abruptly indicates a sudden change or an unexpected obstacle. Driving into water can symbolize feelings of being overwhelmed, emotions taking over, or fear of losing control.

Overall, this dream may point to anxieties about your current path in life and the potential for unexpected challenges. It might be helpful to reflect on areas where you feel uncertain or where you might need to reevaluate your decisions. Consider what changes you can make to regain a sense of direction and control.
