Two of ours like to bite me at night although the biggest offender has stopped randomly biting my feet in the middle of the night. Usually they bite me if I'm not petting them before I go to sleep.
I learned a really good lesson with my first cat, which also coincided with my first marriage. Don't let a kitten bite you ever, no matter how cute it is.
Our oldest is the one who bit my feet and it was probably my fault from playing rodeo kitty when he was a kitten. I used to move my feet and legs under the covers around until he pounced on one then I'd start kicking while he tried to hold on. He's pretty chill most of the time these days but occasionally he'll bite me for no reason. I'm also that his person so he's the main one headbutting me when they need something. My wife's cat will bite me for not petting him in the right place when I'm trying to fall asleep.
God I wish my cats were that simple, but then again I kind of love getting claws in my neck at 4am followed by screams for food.
Oh wait. I don't love that.
