Interesting to read about your dreams. I also have some frequent dreams, but a bit different from yours. I often dream about getting lost as well, or somehow finding myself in an unknown place and I have no money, no phone either, to call for help. It's not a good thing, but if you look deeper, it's kind of the same as yours, when you say you don't see out of the car window. Both means you can't go on, you are stuck (I think).
