Does it mean anything when you dream of your ex and smiling when you wake up?

So, I woke up from a particular dream and found myself smiling a little. What was the dream about? Well, it was about this guy in my class. We had something before but then it ended a few months ago for reasons only he knows actually. Anyways, the dream I had had him in it. And in my dream, I was about to leave when he stopped me and drew closer to me. He was about to kiss me but he backed away suddenly. He placed his arms around my waste and then drew closer again. In my dream, I followed his movement, meaning when he was close enough, I kissed back. It was short. Then he asked, “Are you sure this is okay?”, then he kissed my cheek “are you sure you are okay with this?” then I placed my arms around his neck, gave him a small peck on the lips then I woke up. BUT, when I woke up, I was smiling a little. Here’s my problem, I’m supposed to be moving on, according to my friends he’s not a good guy, but the thing is, i have been having dreams of him recently and some of those times, I barely thought about him. When I smiled, I felt that I wanted my dream to be true, but yeah… it’s not in my hands. Do you think my dream actually meant something or I’m just thinking that it might mean something or something else? Any ideas? Advice?
