Stefan: He spoons you while you guys sleep. Your back against his chest while his arm is around your waist pulling you closer every time you scoot away. He will just pull you closer to him and you would turn around and wrapped your arms around his neck.
Damon: He would lay on his back wile your head rest on his chest. He would wrap his arm around your waist while your arms around his neck. Sometimes you end up on top of him while he tightens his arms around your waist so you wouldn't fall down.
Klaus: He just watches you sleep peacefully in his arms. He likes it when you feel safe in his arms and that you find comfort in them. Sometimes you would stir in his arms and he would gently lay you down on the bed and he would lay next to you and wrapped his arm around tour waist while your face cuddles in his neck.
Elijah: You guys sleep normally. His arms around you waist and your face is in his chest.
Kol: You lay down on your back while Kol sleeps on your chest because he says it is comfortable. While he sleeps you play with his hair and in the next ten minutes you fall asleep as well.
