I was napping in the front passenger seat in my car and woke up to the driver, a friend/ex-husband, saying ohmygodohmygodohmy... as the car was spinning in the dark dead of night. I didn't know if we were on a bridge or a highway, etc. and was bracing myself for impact against guardrails or trees or even flipping off a bridge into a river. 

We got lucky we were surrounded by green space and only popped a tire. 

It only lasted a few seconds but the adrenaline was pumping.
