She sleeps better beside him.
She sleeps best when her head is curled into his chest, and his arm is around her, along with a leg thrown carelessly over.
Her rest is sweetest when it is punctuated with the sound of his silent inhale and and funny puff of exhale, sometimes with a tiny snore.
Her dreams are most peaceful when she can feel him at her back. And when they are scary, the fear instantly subsides when she can roll over and touch him.
Slumbering deeply for hours…it happens most often when her body is in total relaxation after being tangled with his.
Yes, she sleeps better with him.
That is probably why she dreams of him every night.
