1. You're waiting for a train - a train that will take you far away. You know where you hope the train will take you, but you can't know for sure. But it doesn't matter, because we'll be together. - Cobb
2. What is the most resilient parasite? Bacteria? A virus? An intestinal worm? An idea. Resilient... highly contagious. Once an idea has taken hold of the brain it's almost impossible to eradicate. An idea that is fully formed - fully understood - that sticks; right in there somewhere.- Cobb
3. Cobb: (Over the phone) How are you, huh? How are you doing?
James: Okay, I guess.
Cobb: Who's just okay? Is that you, James?
James: Yeah. Is Mommy with you?
Cobb: James, we talked about this. Mommy's not here anymore.
James: Where?
4. Cobb: What do you want?
Saito: Inception. Is it possible?
Arthur: Of course not.
Saito: If you can steal an idea, why can't you plant one there instead?
Arthur: Okay, this is me, planting an idea in your mind. I say: don't think about elephants. What are you thinking about?
Saito: Elephants?
Arthur: Right, but it's not your idea. The dreamer can always remember the genesis of the idea. True inspiration is impossible to fake.
Cobb: No, it's not.
5. Cobb: I'm just doing what you taught me.
Professor: I never taught you to be a thief.
6. Cobb: You create the world of the dream, you bring the subject into that dream, and they fill it with their subconscious.
Ariadne: How could I ever acquire enough detail to make them think that its reality?
Cobb: Well dreams, they feel real while we're in them, right? It's only when we wake up that we realize how things are actually strange. Let me ask you a question, you, you never really remember the beginning of a dream do you? You always wind up right in the middle of what's going on.
Ariadne: I guess, yeah.
Cobb: So how did we end up here?
Ariadne: Well we just came from the a...
Cobb: Think about it Ariadne, how did you get here? Where are you right now?
Ariadne: We're dreaming?
Cobb: You're actually in the middle of the workshop right now, sleeping. This is your first lesson in shared dreaming. Stay calm.
