Are they dreams or visions of the future?

Edwina first dreamed of Klaus von Bruner when she was only ten years old. Since then, not a night has passed by that visions of him haven't haunted her. She has compared every man she's ever known to Klaus, all of them suffering by comparison. The passion she shares with her dream lover frightens her as much as it draws her to him.

Now, many years after her first dream, Klaus has made himself known to Edwina. Who is he, really? WHAT is he? Clearly he wants something from her... something more than the passion shared in dreams.
