In the dream, I was a passenger in a vehicle on a narrow mountain road. I don’t know if it was a truck or car. I did not see the driver. The vehicle started to cross a narrow bridge consisting of a thick solid slab of concrete no wider than the vehicle and without any guardrails. I decided to get out and follow the vehicle, which soon was out of sight. I came to the end of the bridge, where there was a gap of several feet before the dirt road continued to wind along a cliff face and disappear. I had a long view out over the mountainous landscape. I wondered how the vehicle had passed this point. I studied the gap and the cliff face and whether I could jump successfully. The alarm clock solved my problem.
