Movie quotes

  • (..) kill myself to wake up, right? I wouldn't do that if I were you, Mr. Fischer. I believe they have you sedated, and if you pull that trigger... ...you may not wake up. You may go into a further dream state. Now, you know what I'm talking about. You remember the training. Remember what I said to you. (..)
