Paranoid Android

I finally got around to watching "A Beautiful Mind." For those of you who are five years behind like me, the premise is this: A brilliant, socially awkward mathemetician who teaches at a university, falls in love and becomes a victim in a high-stakes government-ordered mission, loses his grip on reality as paranoid schitzophrenia progressively invades his mind. The guy totally mixes fantasy and reality, okay? I'm talking, he makes up people and plots. The whole movie left me wondering if I was really experiencing reality. Was Nadege really sitting on the couch? Was she real? Is her boyfriend real? Are my parents still alive or am I just having these phone conversations with myself? Maybe I'm making up my entire reality. Maybe everyone is. Maybe everyone lives in his/her own world alone and it makes us so crazy we just start making people up!
