I'm walking alone on a paved road up a modest incline toward a cluster of buildings that seem to be part of some kind of tourist trap. There's some commotion up near the entrance to one of the buildings. Turns out some older lady was looking for a restroom and saw a handwritten sign (what it said, I don't know) taped to a door, and alerted the staff, which started this whole complicated process (that was condensed into just a few seconds in the dream) in which a construction crew came out and started demolishing/renovating, and a sinkhole formed and there's lots of confusion about how exactly that happened.
I kind of wander around and observe for a while, but I keep walking, and I realize that there's a big brown lake (see fig. 1 for the color brown) that people are snorkeling in. Families, single people, lots of people, just diving into and wading around in this opaque nasty brown mess. I wonder what they could possibly see beneath the surface of the water.
