At the moment I keep having really vivid dreams about an ex-girlfriend I went out with about three years ago. I haven't seen or spoke to her since we broke up.

Although it was quite a bad break up, from my persepective at least, I haven't given her a moments thought for years.

Now everytime I fall asleep she's there, these aren't dreams of a sexual nature either, lets get that straight.
It's just me and her chatting and a man who is her boyfriend hanging around in a shop we're standing outside.

I can't remember what we talk about, but I know in the dream I can feel an amazing sense of joy and rightness and love for her.

Then when i wake up i just feel gutted and depressed that it's just a dream, I literally feel sick to my stomach that she's with some other guy even though I know it's a dream and I don't even see the boyfriend really I just know he's standing near in a shop(whats that all about!?)

It is so annoying because I felt like that three years ago. Since then I've had numerous liasons, some serious and some not with other women and all that shit was long forgotten.

My mind is fucking with me. what triggers a dream lilke that?
I don't believe that dreams tell the future or any of that crap but I do think that it is your mind shuffling stuff around perhaps?
I don't know it's just fucked up the emotions and memories nightmares can drag up that can go on to affect my whole mood and outlook for the following day.
