Hiatohi was a restless sleeper. She had been that way back when she was Li Hiatohi, tossing and turning all night unless she had something to hug, which was the only way she could sleep peacefully. So, throughout the night, Hiatohi gave full rein to her true nature.
She slept soundly, but Itachi was not nearly as fortunate. Hiatohi's arms were wrapped around his left arm, her legs locked tightly around it as well, making her look rather like a koala, with her head resting softly against his shoulder. She was always like this at home—rolling a futon up into a bundle and wrapping all four limbs around it.
Psychology suggests that people with such sleeping postures are subconsciously terrified of loneliness and betrayal. Well, these days you can slap a psychological label on practically anything, so it was enough to just understand the general idea.
