Last night I dreamt I was trying to hail a cab in a Mediterranean coastal village - I think it was Spain. The sun was hot, the buildings were all made out of sand-colored brick and the locals wore white cotton loose-fitting clothing. I was in a residential area and although I was on vacation (or in backpacker mode) there was some sort of urgency to my needing to get transporation out of this town.
It wasn't fear, just a need to get moving. Restlessness, perhaps.
