Dreaming of her, but she aint there?

So like twice this year, and a few times over the last year and a half, I have dreamt of a girl who I used to be friends with, and Infatuated with to add to that. Two summers ago we started talking and we began to show an absolute interest in each other. We would go out to concerts and plan for more to come. Things didnt work out in the fall of that year, Seems she's been playing with me all along since she stopped communicating with me all of a sudden then appeared at a friends party with another guy, sitting on his lap and all. So after I Verbally lashed out at her in a drunken rage, it was all over.

Within the next few months, we seemed to have re-worked our friendship, and communicated for a few months more, even hinting of a new possible relationship. However, this was not to be, memories of her treachery continued to haunt me, so I sensed she knew all along it wasnt going to be her way this time, and now she's found herself another guy to be with.

We have not spoken personally for many months and its tough because I work with her mother, whom I'm good friends with, and when I see her, I pretend to ignore her which makes it akward, because she doesnt seem to care if I'm there or not. Even though I have moved on, thoughts of her continue to fill my head, now worse the past several months due to her presence in my dreams...

These dreams, I count 4 in total, have gone from me making love to her, although we never had sex. second dream about her dying, not sure how but it was mentioned verbally by someone, third dream it was her in a picture in a pose I liked very much, though i never actually saw her in that pose, and fourth, she was inside a room with the door closed and locked, but her voice could be heard, and this house i did not recognize.

I'm supposing the reason she now appears in my dreams, is probably a hint that we might actually have a future meeting of sorts, like maybe her coming forward with some truth perhaps? In real life I've concluded that she's not even worth another shot, what with her current unknown relationship and my anger towards her, but why does she have to intrude my dreams?! I made up my mind many months ago that I'm going to move on. dreaming of her is not making it easy....Why is dreaming of her even when she aint there brings up emotions? especially since I now seem to hate her for her bad girl ways.

Sorry for the long story, but i thought it would be interesting for some to understand the real life story between me and her, and why my dreams of her could mean something significant or not.
