I have had this nightmare since I was a child. I am riding in a car and we come to a road that has water level with the road on both sides. As we cross the water comes over the road until the road totally disappears. Sometimes I am in a car and develop a sense of dread as I know that around the corner we will encounter the above senario. To this day, I can't stand to drive over a bridge that is close to the water or across a road way with water level on both sides. I had this happen recently as I was on the way to a friends funeral in an area with which I was unfamiliar. Felt like I was jumping out of my skin until I got across. The road meandered through the probably shallow waterway. It was absolutely horrifying. My late sister had the same dream. Don't understand and can't interpret it. It just freaks me out! Thanks for listening.
