Have you tried having sexual intercourse with her? Not to be rude or inappropriate, but I think it'll make you more connected with her as a person and I can almost guarantee that it'll be amazing sex due to the nature of this girl.

Give it a try buddy.
I would strongly advise against doing this. Since you don't know who or what this is, you have to act on the possibility that this is someone real and/or special. You could quite easily anger her or scare her away forever. And if she is a part of yourself, you could completely corrupt whatever this is supposed to represent.

I don't say this to scold Apoc, but I just think you ought to be careful.
