I cannot rember every phase of the dream, but I do remember bits.

I was in a small town from my childhood.  As I walked down a road, I came upon two cars that had been in a wreck.  The people were passed out in the car.  As I walked by, they woke up.   I called 911 to get an ambulance just in case.  My phone kept getting disconnected, and I could never complete the call.  For some strange reason, my phone was being modulated like a synthesizer.
