I too had a semi-Freespace-related dream about a year and a half ago, and I too was somewhat sick at the time. You see, I was just getting into learning FRED at the time, but I couldn't make heads or tails of the code. The ways the sexps & such were linked together made absolutely no sense to me. That night, my frustration with trying to grasp the basics of FRED manifested itself in a dream that seemed to make no sense. None of the images in the dream would be imediately be recognized as being of Freespace or FRED origin, but I just remember that it represented FRED. It was like there were hundreds of geometric formations around me (which I guess were the various sexps) that I was attempting to organize and string into sequences that made sense, but I was becoming inundated with them. It was kinda claustrophobic.
