Dreams were an escape that Hermione took advantage of whenever she could. When she was younger and determined to make her own mark on the world, or at the very least prove that she belonged in the world she was a part of, she would sleep as little as possible just to keep her body functioning. The human body really needed very little to keep going. Though she was well aware that it wasn't healthy to skip sleep entirely, she always imagined that there would come a moment in time when she could slow down enough to actually get a full night's sleep. Once she was finished with exams, she could sleep. Then, once she was finished with her summer coursework, she could sleep. Oh, but then she had to read all of her schoolbooks before the beginning of term to make sure she wasn't completely ignorant of the subject matter. But, once she was in the castle, there was always something else that kept her from allowing herself to relax.
