The two major scenes I recall in the dream were fixing this 'interactive' fountain art installation, and then being in control of the liquid projection visuals for some kind of performance.
The fountain was composed of many levers controlling 'drinking-fountain-like' spouts. These spouts were controlled either by simple 'bar-valves' where you could turn them left or right to open or close them, or clasp-like 'triggers/latches.' Water was leaking and shooting in random directions and people had given up on trying to fix it. It kind of looked like a pipe organ meets telescoping stands meets drinking-fountains. Basically through a process of trial and error, logically following the flow of the water, closing valves at the end and/or before leaks, and then reopening other ones, some semblance of aesthetic beauty was restored.
I had parked my car across the street from the banquet hall in which some big event was happening... The parking attendant said, if you fix the fountain, I won't ticket you. So that's why that whole thing unfolded... Then there was this situation where we were dispersing from small groups in this one ballroom and going back to the main banquet hall. People were starting to put food away in one section and saying that I couldn't have access to it. I explained that that didn't make sense because our group activity had just ended and we had come straight from that to come eat. They insisted and I pleaded, then I turned around to see another buffet set up where friends of mine were serving themselves. One of my good friends, Jason, was minding the line and I said "can I eat here?" To which he said no, and that's when I got upset and we argued and then I began to plead with him eventually saying, "I'm eating this food no matter what you say." I dono why I was so hungry in the dream...
When I sat down at a table to eat, a group of performers came on stage. Then the next thing you know I'm sitting next to a device that looks like a volcano vaporizer, except instead of a heat-source there was a light. On top of the volcano was what looked like the wax of many melted candles of different colors. It was malleable like play-doh, and it would melt in the light. The light was also a camera, so the things I would do would be projected on the screen behind the performers. The resulting projection/effect was that it basically looked like colored liquid-smoke that was endlessly kaleidoscoping as I would knead it together and then the light would melt/thin the wax to be remoulded into a more uniformly dense glob. An on-looker was fascinated that I 'knew what I was doing' and asked me if I was a pro. I said that all of these things: fixing the fountain, playing with the wax... were done intuitively. I was wondering why nobody had stepped up to work it before me. Then a representative from the performance troupe came up to me and wanted to hire me.
Before all of that we were in another ballroom and were split into groups of 5 or 6 and were doing these interesting 'dance' or 'acro-yoga' exercises? I actually just remember watching two groups go before being directed to do something else. These groups would be seated in a circular fashion, and then would grab the ankle or a wrist of one or two of their neighbors, then would collectively stand and then jump around in a circle still holding a limb of the neighbor. It looked very "Native American" to me... Someone told me to ground myself before doing this exercise by stretching and crossing one leg over the other and then isolating certain muscles.
