SCULLY: ... I believe that the victims were suffering from something called Waxman-Geschwind syndrome, the symptoms of which are trance-like states, leading to vivid dreams about the past-- dreams that are more detailed than the conscious mind can recall. It's also called Dostoyevsky syndrome because the Russian novelist was suffering from it, too.
SCULLY: Where is he now?
GOLDSTEIN: I don't know where he went.
SCULLY: What was the last thing he said to you?
GOLDSTEIN: He said he was going to exorcise his demons.
MULDER: I'm so tired. I need to know, Scully. I just need to know.
SCULLY: (voiceover) ... Agent Mulder undertook this treatment hoping to lay claim to his past--that by retrieving memories lost to him, he might finally understand the path he's on. But if that knowledge remains elusive, and if it's only by knowing where he's been that he can hope to understand where he's going, then I fear agent Mulder may lose his course, and the truths he's seeking, from his childhood, will continue to evade him...driving him more dangerously forward in impossible pursuit.
