"Should I see a psychologist about these recurring dreams?"?

I met this person like a year ago, he was into me but I wasn’t, I tried to avoid him but he kept trying to be with me for like 3 or 4 months then, out of the sudden, I had this dream where he was my longterm boyfriend and he was in a reunion with my family, after that, I just fell in love with him. I tried to solve things with him but by then things were really fucked up, he never took me seriously again so I never told him my feelings. I gave up cause I was coming back to my country and he’s American. I left USA three months ago and I haven’t been thinking about him at all but lately I been having this dreams about him every night, Why am I dreaming about him when Im not thinking about him? Do I need to go to a psychologist?
