Submission: Dreaming About My Ex Boyfriend

I keep having dreams about my ex, these past few weeks. And I don't know why. We've stayed friends, but I've barley talked to him, in the last 6/7 months.  He's been impossible to get ahold of(that's a whole another story)  Anyways, I 'm kinda wondering why, he keeps popping up in my dreams! I've finally moved on,which ended up being extremely difficult(again, another whole story) I don't know a whole lot about dream interpretation, other then the theory that dreams is your sub-conscious talking. Anyone have insights to why I keep dreaming about him??

update: last night I had the strangest dream with him, I was roommates with two of my friends(one of them I am actually going to be living with soon) In the dream my ex didn't live to far from me(in real life he does) He had just broken up with his gf(in the dream), the door to his apt. wasn't to far from mine, and random women kept walking into it.  Then something about myspace pages came into the dream, he created one and I wanted to add him as a friend so he could hear the song on mine(which really is the song i have on mine, and it does remind me of him) Then I woke up around 5am-ish(really woke up, not in the dream) with a song stuck in my head, that was playing in the background in parts of the dream(not the myspace song though) and the song is "why haven't i heard from you." I've had some strange dreams about him, and other things, but this one is def. one of the stranger ones. Any interpretations?
