Her first conscious thought -- that didn't involve chocolate, birds, or chocolate birds -- was that this was how her father liked to wake her when she was young. He'd attack, and rolling over for more sleep hadn't been an option. She had to be ready to defend herself at a moment's notice, even while half-asleep. So she kept pressing the attack on pure muscle memory.
That sobering thought broke through the fog of sleep, rendering her instantly alert. Under normal circumstances she'd be awake the moment he opened the door, but she'd pushed herself so hard and lost so much sleep over the past week.
She saw that Dick was in the room, having just fended her off. "Oh," was all she could think of to say.
She nodded a 'good morning' to him, then she spotted the mug of hot chocolate. That explained some of the details of her swiftly-fading dream. She grabbed the mug by the handle, and she almost chugged it right then and there, but she remembered in time that it was hot, so instead she blew cool air across it.
