"Dean?" I heard Sam's whisper through the haze of sleep. Next thing I knew, he was pressed up against me, his back to my chest. I made an unintelligible sound and blinked. The hotel room was dark. Sam looked over his shoulder and I immediately recognized the panicky look in his eyes.
"Have another nightmare?" I mumbled blearily. Sam nodded and shifted closer. I wrapped an arm around his waist and tucked my head into his shoulder.
"Want to talk about it?" I asked, muffled.
"Just need you, Dean." He murmured, and I made a satisfied noise and pulled him tighter, sharing his heat.
