To me your dream seems to suggest fears of being trapped in an unpleasant situation. I always took dreams to reflect unresolved feelings of either fear or desires. I don't know if I am right. I had a somewhat similar series of dreams recently, during a trip to the ICU with a bad flue bug, while coming off some meds that I had been unable to keep down. It started out looking like it would be okay, but grew more fearsome and anxiety provoking as the jouney through trashy places, surrounded by disfigured individuals continued. I thought the dream would never end. But it did, and I can only consider it an unresolved fear of undesirable places or circumstances. May you never dream such a thing again!
