I've had a similar dream, driving until the road gets covered with water. After I met someone I thought I would marry, I had one last dream where my vehicle went into the water and I tumbled out. In the dream I was not scared of the water, but in real life I would be terrified if that happened. Until I read this message I hadn't even thought of that dream in over 2 years, the time I was socially active. I used to have the dream of driving on a road that was flooding or being hit by a wave at least once a year. Just kind of odd. . .
