COBB: They’re projections of my subconscious.
COBB: Sure-you are the dreamer, I am the subject. My subconscious populates your world. That's one way we get at a subject's thoughts - his mind creates the people, so we can literally talk to his subconscious.
ARIADNE: How else do you do it?
COBB: Architecture. Build a bank vault or a jail, something secure, and the subject's mind will fill it with information he's trying to protect.
ARIADNE: Then you break in and steal it.
ARIADNE: Why are they looking at me?
COBB: Because you're changing things. My subconscious feels that someone else is creating the world. The more you change things, the quicker the projections converge on you.
COBB: They feel the foreign nature of the dreamer, and attack-like white blood cells fighting an infection.
ARIADNE: They're going to attack us?
COBB: Just you, actually.
ARIADNE: Mind telling your subconscious to take it easy?
COBB: That’s why it’s called subconscious. I don’t control it.
ARIADNE: Why couldn’t I wake?
ARTHUR: The only way to wake from inside the dream is to die.
COBB: She'll need a totem.
ARTHUR: Some kind of personal icon. A small object that you can always have with you, and that no one else knows.
ARIADNE: Like a coin?
ARTHUR: Too common. You need something that has a weight or movement that only you know.
ARIADNE: What’s yours?
ARTHUR: A loaded die.
ARTHUR: I can’t let you handle it. That’s the point. No one else can know the weight or balance of it.
ARTHUR: So when you examine your totem... You know, beyond a doubt, that you’re not in someone else’s dream.
COBB: Inception. Don’t bother telling me it’s impossible.
EAMES: It’s perfectly possible. Just bloody difficult.
EAMES: What’s the idea you need to plant?
COBB: We want the heir to a major corporation to break up his father’s empire.
EAMES: See, right there you’ve got various political motivations, antimonopolistic sentiment and so forth. But all that stuff’s at the mercy of the subject’s prejudice you have to go to the basic.
COBB: Which is?
EAMES: The relationship with the father.
