This made me laugh as I remember Carrie (my first ever cat, sadly died 2 years ago) used to wait for our feet or legs to move under the duvet before pouncing on them! Once she'd finished 'playing' she'd sidle up to my pillow and claw back the covers to get into the bed with us before settling down with her head on the pillow next to mine
All was well each night until she'd decide it was feeding time and wake me up by pawing my hair and trying to lift my head off the pillow with her paws.
Another of her tricks to get me up was to slowly sink her claws deeper into my scalp until I either got up or nudged her away.
