What do these dreams might mean?

Well, I've had two dreams over the past month, and I was really wondering what they meant. The first one was when I was dating this guy. In the dream, I was lost in this white misty space. For some reason, I was really upset and confused. I kept on trying to find a way out or find something. After that went on a while, I saw my boyfriend at the time. So I ran up to him and was crying. He then hugged me and smiled, but said nothing. I cried for a long time and finally said,"I haven't been hugged in a long time." He smiled again (it was like he knew something, I guess?) and kept hugging me. I woke up sometime afterward, smiling. And then a few days later, he broke up with me. The second dream was a week ago with the same person, and we were in one of classes, and we were reading on the couch. He was so happy for some reason, and kept talking to me (I can't remember what he said, but he was joyful about it). He would lean on my shoulder and lean his head in my lap, while I was so confused. I kept asking myself, why was he speaking to me? Why was he being nice? I thought he was through with me? Then I woke so confused and bewildered. Some possible explanations would be nice. :)
