Anything that comes to mind, put it in the story.
A young, blond girl laid on the cold pavement in the middle of a park, on a warm summer night. She was staring up at the stars, as the moon shone brightly down on her. Closing her baby blue eyes, she began to drift off into her dream world, where everything made more sense, and where everything was wonderful, not screwed up like the real world. She'd sometimes finding herself wishing that she wasn't here at all, that she could find somewhere better to be, but deep down she knew it'd never happen. The real life world would always been a hard, messed up place, it'd never change. She knew that, but it didn't stop her from wishing it to be better.
