Looks at you from behind. She is the reason behind the inappropriate dreams you see everynight. You see her whenever she wants in whatever role and shape she wants but you will one day meet her intimidating real self. And that's what she is going to tell you:

No no no....those were not nightmares, they were dreams. ... and let me tell you.... I never had any control on you or your thoughts. ... it was you who liked to think that way, ....I didn't make any of those dreams.... you did that yourself. Those dreams were nothing but your real desires within you. Don't lie to yourself... you always had them and you know that. .... you wouldn't remember them right now if you didn't like what you saw everynight.
