I remember a game I used to play where a girl, when she slept, would fight bosses with the help of stuffed animals; if I’m not mistaken they were her relatives, and there was a shelf with stuffed animals representing the bosses. You could also go to the mother’s room when she was awake. I don’t remember the name but I really want to play it again, the text is a bit confusing.
Could it be Among the Sleep?
