In her most recent life, Buffy was consumed with bad dreams - monsters, her deceased family, her dead friends. She did all she could to stay awake, hoping to keep her terrors at bay. She failed.

Buffy, reborn by Hydaelyn, continues with many traits - courage, loyalty to her friends, her need to protect her lovers. But she is also softer, more caring, more willing to slow down and see Eorzea in its glory. Also, no more bad dreams.
