That I can't answer with any certainty. It does seem that our powers are altered to fit this world in some way, such as magic requiring mana now based on dreamotion energy instead as the source. But as to the specifics or how I don't think anyone really knows. Thus if you have some kind of "darkness" or "dark power"...the chances of it becoming more attuned or changed to nightmare energy is not improbable.

What exactly is this power? And how have you managed to control it until now, both in your world and this one?
