Why would I be having a dream of my ex?

Last night I had a dream about a guy that I have dated more than twice before and I always end up losing feelings for him. I have always wondered why, but my dream was circled around me and a few people at a party. (like a house party you see in movies, but not as dramatic) I was talking to a woman I use to go to school with and my eyes turned to the middle of the house to meet my ex boyfriend's eye's. I quickly looked away and continued to talk to my friend. Little time later, I was outside catching a fresh breath of air, but once again he was there. This time he ran up to me and hugged me. One of those hugs that you could almost tell the desperation that neither of us wanted to let go. I began to cry, as if I was disappointed. I wasn't necessarily weeping, just tears slowly falling on my cheeks kind of thing. I kissed him on his cheek and that was when he slightly pulled away and said, "just hold on." My dream then cut to us going under a breezeway, at least I thought it was close to that, and we talked about my car and a few more things. I just want to know why I would be having this dream.

Dear priest ogidiga, Thanks for everything. You are the best among all the spellcasters I tried these last months. They gave me little results but none of them did what you done. I hardly believe this but you just fulfilled my dream. I say it again: You are the best my husband is back. any one look for help should visit him on email him on [M I R A C L E C E N T E R 1 1 0 @ G M A I L .
