I was looking through the audio files in the Command and Conquer Demo disk, and I found something really weird. In AUD.MIX, the files with ID FA2D0EBD and ID FC2D0EBD are both excerpts from Stephen King's Insomnia.
FA2D0EBD is a sped-up version of "but lack of sleep is the least of his worries," which seems to be an excerpt from the synopsis, while FC2D0EBD, when slowed down, says "that walking was not exactly what they were doing; it had seemed more like gliding. They went from the picnic area at the end of Runway 3 back to Strawford Park in that same fashion, only the glide was faster and more pronounced now. It was like being carried along by an invisible conveyor belt. As an experiment, he stopped walking. The houses and storefronts continued to flow mildly past. He looked down at his feet to make sure, and yes, they were completely still."
FE2D0EBD says the same, but reversed, while 002D0EBD seems to say something about "cortex stimulation" and "rapid neuroleptization," phrases that from my brief searches don't appear in the novel.
Having never read the book myself, I have to wonder if it in any way ties into the themes of Command and Conquer, or was it simply chosen as creepy throwaway dialogue?
