Quote from : Catching Fire Book

Peeta, how come I never know when you're having a nightmare?” I say. “I don't know. I don't think I cry out or thrash around or anything. I just come to, paralyzed with terror,” he says. “You should wake me,” I say, thinking about how I can interrupt his sleep two or three times on a bad night. About how long it can take to calm me down. “It's not necessary. My nightmares are usually about losing you,” he says. “I'm okay once I realize you're here.
