another weird dinosaur train dream I had

This was only a vague memory of what I had dreamt. Mr. Troadon the conductor had taken me on a tour inside of a volcano.  I'm not sure what he reason was, but he took me into an elevator and when we took the ride, suddenly the  floor of the elevator began to fill up with red hot lava, which was yellow for some reason, but it was extremely hot. My feet didn't get burnt, but at the end of the tour, I  remember how exhausted and tired I felt upon trying to catch up with Mr. Troadon to get back to the dinosaur train.  Oh there was something also weird about flipping switches to activate something and trying to translate some ancient code written on the wall.  Weird.
