Carl Jung discusses the morning and afternoon of our lives. Sounds similar to your "wake up"as Rip Van Winkle descriptor.

“Thoroughly unprepared, we take the step into the afternoon of life. Worse still, we take this step with the false presupposition that our truths and our ideals will serve us as hitherto. But we cannot live the afternoon of life according to the program of life’s morning, for what was great in the morning will be little at evening and what in the morning was true, at evening will have become a lie.” -Car Jung
