In practice, putting it the way this advice does is basically designed to make her defensive and refuse to listen to you ever again (ETA as evidenced by the comments, which you are right, I should not have read). If the goal was to express your emotions at her, then it's fine, you're allowed to do that, but if you actually want to help out a friend, maybe put it more gently than "your dreams are offensive to me personally". Maybe something more like "It is nice to dream about having that kind of glamour, but I myself can never get past the horror that lurks in the background of those kinds of settings." And see where it goes.
