Once upon a time, Rose's sleep was frequently interrupted—much to her irritation. In the beginning, she absolutely hated it, positive that each time it happened she would wake up drained and exhausted, which was the last thing she needed considering she had to get up at ungodly hour for training—and she was already seriously sleep deprived from Lissa's little midnight trysts.
As time passed and she slowly got used to the bizarre concept that the unusual dreams didn't actually affect her sleep, her irritation at the encounters faded and she actually kind of enjoyed them—although she never admitted it. Even then, she never thought that she'd miss the dreams if they were gone—and she never really stopped to appreciate how much painstaking effort went into weaving those fantastic dreamscapes in an attempt to please her.
Not until she stopped having them.
Now, she would give just about anything to have Adrian interrupt her sleep with his illusions again, because it would mean that she finally had her friend back—even if it was only for the length of a single spirit dream.
