Dream: A hotel where some doors opened onto a dune landscape, desert or ancient beach.
We went through one of those doors, and there were massive drifts of gemstone pebbles which people were collecting.
Near sunset people were gathering to see the annual miracle, and some were putting their stone collections by a shrine which also had elaborate stacks of vintage glassware.
When the miracle was over, hotel staff moved walls to cover all the doors that led to the dunes. I slipped back in.
