floating history

I dreamt I was in a history class of sorts. It felt like a field trip. We were on these individual platforms that we could sit on. A few could share or some went one by one. It is as if the platforms floated through the air and we could go through a history book visually. First we were in a cavern looking type place with dim lighting. There was a map across the ground that was 3D, yet still simple... countries were colored pink, green and yellow etc, and they were labeled. You could just see some raised areas where there would be mountains. Then we went through an arch way. There were floating columns, artifacts, and you almost felt like some of the air from the past. I felt like we were seeing things that may not exist anymore, but they were real all the same. I was so excited as I had wanted to be an archaeologist. I was right here, with the past. It was amazing. Then there were these red and yellow things on the ground where we got off of our platforms to get a closer look at the artifacts. They were crawling along the rocks and boulders. At first they looked like slugs and then they appeared to be long "haired" caterpillars. I warned everyone to watch out and not squish them. Some had already been smeared on the rocks. Then George Bush showed up out of no where to give a speech. "My fellow citizens. Today I am here to talk about peace ... P S S S .. " I started laughing in my dream... I was thinking figures.... Then he mentioned something about religion and Sister McJesus.
