After seeing Inception, I looked up the definition of schizonphrenia:
"Schizophrenia is a serious mental illness characterized by a disintegration of the process of thinking, of contact with reality, and of emotional responsiveness. It most commonly manifests as auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking with significant social or occupational dysfunction."
That pretty much sums up what you will feel like for a few hours after watching this movie. Good luck!
