" 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.
ARIADNE: Converge?
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. "
