Cheating on my boyfriend with an unknown man

[teletups]

Last night I had a dream about cheating on my boyfriend. We have been together for 6 years, I love him with all my heart. But like all relationships, we have our ups and downs. Lately he has been super busy and stressed with work and I am kind of sad that he doesn't give me enough attention. I understand but sometimes it makes me sad.
So here is the dream.
I was cheating on my boyfriend with some guy that I have never seen in my life. The way this person made me feel in my dream was amazing, I have never felt like this for anyone. He was so nice, loving, caring. We didn't have sex, but we did made out. What happened was that he told my boyfriend that I cheated on him. Of course I felt horrible for doing that and I was asking for him to forgive me. I think he was considering to forgive me, but I didn't really care. Because I was still thinking about this other guy.
And I can't stop thinking about him right now either. I have never seen this person, but I know he was the perfect guy and he was the one for me.
What does this mean? Is it possible that I am making up this person and the way I felt in my dream because it's lacking in my real relationship. Is there a possibility for me to ever find this person?
