Snungster: I enjoyed your post. I agree with you that the film didn’t clarify why, or even if, Peter was actually being treated by the military for anything, or even if he was actually ever in the military; and if he was in the military than he was probably mentally ill prior to his service. I also thought R.C. bringing Peter to Aggie’s room and then leaving him there was very odd indeed. However, I think that was probably just an awkward place in the script - “Hmmm…how do we get Peter to Aggie’s room?” LOL
I do not think that Peter's mental illness had anything directly to do with the government or the military. If he is suffering from PTSD, post-traumatic stress disorder, the symptoms are greatly different from the way he acted in the film. I believe that Peter is suffering from the mental illness of paranoia
My brother has a close friend of over 25 years who has always been anti-government and believes in government conspiracies, but just over two years ago she reached the point where she became openly paranoid. She now refuses to leave her apartment, will no longer use a telephone, cell phone, television, computer, or even listen to music because “they” are watching, listening, and trying to implant things in her head and so forth. It is heartbreaking. They are wealthy and can afford the best care, but she refuses to see any type of doctor and her husband will not commit her to a hospital.
She lives next door to my brother and he says that every day her attitude and demeanor are different. When he does manage to see her, she may be hateful, secretive, distrustful, crying, or will whisper to him about the people who are out to get her. Often she will not open her door. On occasion he will see his old friend, as she used to be. It is very, very sad. If she lived alone I have no doubt she could easily end up, in her own way, like Peter.
Peter is probably suffering from persecutory delusions or may be a paranoid schizophrenic or may have a paranoid personality disorder (credit here to Wikipedia - I’m certainly not a psychiatrist!). A lot of the film is viewed through either Peter’s or Aggie's point of view, although the director doesn't make that obvious. For instance, I wondered about the helicopter at first, the bugs, and Aggie's son, but once I realized they were both feeding off of Peter's paranoia I settled back to enjoy the ride. What fun!
