The other reason the sneak peek is in Nicks head. It centers around the ax. Nicks knows to dispatch a hexenbiest he needs the ax. Like with other wesen certain weapons are more effective then others. This is knowledge that Nicks has but Juliette doesn't. If Juliette does not know the significance of the ax she would not dream of Nick using the ax. But I don't even think it is a dream. What we are seeing is the writers a providing a narrative. Sort of a what if are someone expaining what could happen if Juliette is not able to control being a hexenbiest. The other idea is Nick has the ability the sense wesen. Juliette has not told Nick she is a hexenbiest, but Nick keeps getting this feeling the Juliette is a hexenbiest. When awake he rationalizes it must be because of the switch that got his Grimm back. In his dream is rationalizing why he feels that Juliette is a hexenbiest because Adalind morphed as Juliette.
