E.L. James likes to end scenes with falling asleep, because it's quick and easy and because she learned all her writing skillz from the second grade. If the last page of this book says "it was all a dream," I QUIT LIFE.
We start chapter 17 with -shock- Ana waking up. She was dreaming of a candle flame and she's a moth flying right for the light. She says, "I'm flying too close to the sun," and even though she doesn't mention Icarus, that's like a copy paste from two pages ago.
Ana realizes that she's dreaming of hot things because Grey is draped across her and his body is making her hot. I know this is really nuanced writing here, but try to keep up.
We're told that Grey's body heat is suffocating Ana. If we've learned anything from all the times her breathing has failed her, though, it's that Ana lives not by oxygen alone. I think she actually breathes gray eyes, abusive relationships and hating Katherine Kavanagh. She proves this by taking a moment out from suffocating to be really happy that Grey spent the night in her bed.
