Ok... onto the archetypes. It is not unusual for me to dream about animals in my dream. It is incredibly common for me to dream about invasion / end of world stuff. I'd completely miss disaster precognition stuff in my dreams because the events happen so often.
The punch line is that the guys in the future used virtual reality rigs. Apparently one other guy came from the past and he was insane. He infected the VR equipment with his madness and it looked like the cycle of running and hiding was beginning again.
