Nightmare

In a dream a friend was standing with me on a sidewalk in New York City. She was offering me a subway token as we approached the below-ground entrance. "I have two," she said. I begged off, feeling too ashamed to take one. The next moment we were in a car on the highway. My friend was driving. We came to a complete stop at a traffic jam. Suddenly the car was moving freely again - because we were going in reverse at high speed! I winced, imagining we'd be crushed at any moment by an oncoming vehicle. My friend was looking at me and cackling, not even glancing in the rear-view mirror. I didn't want us to die. What to do? Pull the keys? Take the wheel? I opened my eyes.
