Real Nikki used the OWW as an act of revenge on Bear

So, in the end Nikki uses the OWW on the table to make Bear fall in love with her. From what I saw in online discussions, this action is performed by Freaky Nikki, which doesn't make sense to me.

Freaky Nikki exhibits unnatural and erratic behavior. She obeys Bear without regards to the human body she possesses (when she creepily smiles and stays peeing and pooping at the front door). She can't even mimic human behavior or display normal adult functions (she 'reads' a book but it is upside-down). That can't be an entity that: pays attention to some random object on the table and then reads and understands what she can do with it.

My theory is that for some reason real Nikki temporarily regained control of her body, read the instructions and made a similar wish so that Bear would lose his autonomy and "love Nikki more than anything in the fucking world". (sorry if this was already discussed)
