Underwater Spa

Two good friends and my wife were along with me to visit what would best be described as an underwater spa. We dove into large structures containing pools of water. The structures were all underground and appeared to be made of a fine and soft wood. We would swim through these structures and come up for air at one of several areas designated to improve mind, body and health. I cannot remember what the first point was but during the second dive, we came up in an area designated for some kind of group steam bath. There was a leader standing atop tiered wooden platforms where people would lay down next to each other (in near perfect order) and obey the commands on the leader- when he said to turn over, everyone did so. When he said to lay on your back, this was done. The steam and heat were enjoyable and we began looking for spots to lay down at. It was just then that my friend had fallen off a tier and on to another one just a half foot down. He fell onto someone else and I laughed.
