Virtually everyone in my family has had that dream, which is also featured in the 1980s spy spoof Top Secret. It seems to be pretty popular.
I have a favorite theme that not too many others share. I get stuck driving down a road that leads inevitably--no exits--to some dazzlingly high bridge or overpass. I gun the engine and go for it but the higher I get, the nearer to vertical the road gets. I usually wake up in a panic before I get over. Sometimes I start to fall, or stop in the road and scream my refusal to go any further as horns begin honking behind me.
