sand river

I dreamt that I was on some large truck or train. It was supposed to carry many other semi-trucks in the back. It wasn't my business or job, but I decided to organize it better or not sure exactly, but it made it possible for all of the trucks to fit and they would only have to make one trip. This made the people, and my dad who it seemed it was partly his job, happy. We had some spare time so I went and walked around outside. It was like a desert. We were surrounded by sand and some rocks and there were workers milling about finishing up things. I walked along the sand over to some boulders. I saw that they were carved. Some archaic, some intricate. I wondered if any of them were old if they had been recent. I looked at one and it had a date of 1997, but then another one looked faded and worn like it was actually very old. On the ground near the boulders there were some more items that looked like artifacts. They were stones but with a glass top like someone had fused the glass on top and put items in the glass for decoration. They were very unique. I picked a couple up to see if I wanted to take one home. One was more attractive visually with just lines in the glass, and one was a bit more gaudy. I normally would have liked the less gaudy one, but for some reason I felt the gaudy one had more meaning or more of a story to it so I decided to keep that one. Near where I was walking I could see the sand moving. It was like a long line of sand that was going in one direction, but only in that line, then it kept getting wider and deeper. I wondered if this was normal, if this had been happening for years? But it couldn't have been. It moved too fast and changed too much. I wanted to talk to someone to see if this was a bad thing? or just a ??
