Good night YUSUF: The compound we'll be using to share the dream... Creates a clear connection between dreamers... ...whilst accelerating brain function. In other words, more time on each level Brain function in the dream will be about 20 times normal. And when you enter a dream within that dream, the effect is compounded it's three dreams, that's 10 hours times 20 Math was never my strong subject How much time is that? It's a week, the first level down Six months the second level down and the third level- That's 10 years Who'd wanna be stuck in a dream for 10 years? Depends on the dream So once we've made the plant how do we get cut? I'm hoping you have something more elegant than shooting me in the head. - A kick. - What's a kick? EAMES: This, Ariadne, would be a kick it's that feeling of falling you get that jolts you awake. - Snaps you out of the dream. - We gonna feel a kick with this sedation? YUSUF: That's the clever part I customized the sedative to leave inner-ear function unimpaired. That way, however deep the sleep the sleeper still feels falling. Or tipping The trick is to synchronize a kick that can penetrate all three levels.
