But what if Sam and Dean slept in the exact same positions every night, so in tune with each other because of the decades of sleeping in the same bed, one of them spooned up behind the other (the role of “big spoon” changed over the years when Sam got to be taller than Dean and thought it would be more comfortable to be behind Dean. So one night he climbed in behind and they both slept like that ever since)? Even when they fought and slept in different rooms or cities or states they would still curl into bed in position; Sam’s arm tucked under his pillow and other arm thrown out in front of him, his back bent forward slightly to curl against Dean’s even when he wasn’t there, and Dean’s arm closest to the bed curled against his chest, fist under his chin and other arm propped on his hip, as if Sam’s arm was slung across it and their fingers were tangled together. But neither of them could sleep alone very well because Sam’s extremities were like ice at night so he would press his toes up against Dean’s calves and Dean would radiate heat against Sam’s stomach, so Dean’s legs would be too hot and Sam’s chest would be too cold when the slept without each other.
