[Quaid points a gun at Dr. Edgemar's head]
Douglas Quaid: All right, let's say you're telling the truth and this is all a dream. I could pull this trigger and it won't matter.
Dr. Edgemar: It won't make the slightest difference to me Doug, but the consequences to you will be devastating. In your mind, I'll be dead, and with no one to guide you out, you'll be stuck here in permanent psychosis. The walls of reality will come crashing down around you. One minute, you're the savior of the rebel cause; next thing you know, you'll be Cohaagen's bosom buddy. You'll even have fantasies about alien civilizations as you requested; but in the end, back on Earth, you'll be lobotomized! So get a grip on yourself, Doug, and put down that gun!
