Bridger's Oneironautic Expeditions

I'm walking around a cool-looking amusement park that also has many water attractions. I get in line for one I've never seen before. It's a frozen pool area that's surrounded by a building. It's supposed to be relaxing. Around 30 or so people go in at once and as we walk across the ice, I do yoga poses as I slide along the ice trying to get relaxed. Everybody is looking at me funny but I keep it up until we walk to the side of the pool we're supposed to be on. When we get there, I start to notice the ice looking thinner. I mention this to some people, but it seems that no one is troubled. Suddenly, I fall through only to find that the water is warm, like a hot tub. Gradually, the ice melts away and the frozen pool is now one giant hot tub. Side doors are opened up for people to come and go.
