Only in Dreams

I was somehow trapped in the past. There was a mixture of future as well, as if the future now had somehow become the past somewhere else. Time just cycled. I was on an expedition with a group of people and we were exploring an old pyramid system that was discovered in a cave in Cambodia. Green vines snaked and engulfed the mayan-esq ruins. We had found entrance into the main pyramid and within it was a type of holographic computer system. Letters and symbols spun within boxes much like the symbols on a slot machine. The screen and interface had a tinge of green to them. Inside I remember hearing a song by Jack's Mannequin where the chorus says "Sky Blue, Sky Blue. Have you ever been alone in a crowded room?" We knew that inside this system had the clues to developing/using an advanced missile launching system. Possibly built into the pyramid structure. I stepped outside to contemplate how to unlock the system. As I walked around, I discovered large blue crystals partially buried in the sand. I picked up some of them and then it clicked. I rushed into the inner chamber and looked through the blue crystal at the interface and the numbers seemed to stop spinning and started to spell out phrases. It actually reminded me of wheel of fortune. I felt the urgency to get out of there for some reason. Possibly the same reason that once the group started to crack into the system and unlock the data, the stone doors started closing and the water began to flush out of the pyramid and fill the cave and corridors. I was outside but only a few people made it with me. The others had to find some sort of release mechanism to get out. I started to scramble up the side of the pyramid as water filled in around me. Luckily, the others who were inside found their way out and on top with me. We climbed through a vine-filled hole in the ceiling and out into the jungle above. Ever since they activated the weapons system there was this urgency pressing my mind. This feeling was escalated as a Tyrannosaurus burst out of the brush behind us and started charging to eat us. Naturally we ran and along the way of dodging trees and such many of us found bicycles to ride. This made the getting away much easier. A native started riding a bike past us but someone knocked him off and next thing I know, they were on his bike making a clean getaway from the dinosaur. I had a sick mountain bike and I was ramping over roots and such escaping with ease.
