Just your subconcious sorting things out. Just a dream....and some regret.
It means it's not over yet in your mind.<br />
But if you're sure it's over, and it must be if she dumped you, then you'll have to accept it, and do that thing we hear so much of: "Move on".<br />
So easy to say to others, so hard to do yourself.....
Oh, it's just part of the cycle of heartbreak. I had dreams/nightmare for over a year about one man who broke my heart (and the 'friend' who grabbed him away before our bed was even cold...)<br />
They'll subside eventually, these dreams.
