I seem to have misinterpreted the book when I read it and I'm hoping someone can clear it up for me. I got the impression that Mr. Gray was a total fabrication in Jonesy's mind and that he was never actually taken over by an alien force. It has been a few months, but I remember 2 reasons why I thought that. The first was that Henry told Jonesy something about Mr. Gray stopped existing at Hole-in-the-Wall, and the second was when they were with the government doctors in the epilogue Jonesy is able to revert to Mr. Gray while under hypnosis. Every topic I've read in this board about "Dreamcatcher" makes no mention of this so I'm assuming that I veered off course somewhere around Jonesy and Henry at the "hospital" bed with Mr. Gray. I intend to give the book a re-read before my last 3 "Dark Tower" novels arrive from Amazon next week, but I wanted some clarification before I started again.
