Is there a word for people who are oblivious of the atmosphere around them? [closed]

For example, is there a word to describe a little girl who just sits on the sofa watching tv happily while her parents are fighting — as though she were in her own "happy place" and behaving normally?

This is for an art assignment. I have to draw a picture illustrating a word. I want to draw a scene similar to the one I described, but I don't know any words that would fit.

engrossed
