Would it be considered stalking if....

So, there is this guy that i know, and have know for quite a while, and i can't stop wondering how he is. I met him the day that i graduated from massage school. He is handsome and super nice and we hung out for a while. He lived in Chicago, and would have to come up here on business and we would go out and have a blast! We never did anything date like, but he was kind of sweet on me. And for some reason i have been having dreams about him. So weird! In my dreams his head will be on my girlfriends bodies and stuff... ok that is creepy but weird non the less. So i have been wanting to get back in touch with him.... Problem is, i can't remember his last name, and i don't have his number anymore. I think that i may have his number in one of my old phones, but i am just not sure if i do. I have tried tracking him down on facebook, but without a last name that is next to impossible. He worked/ maybe still does for BMW so i went on that website to see if by chance they had a company directory, but i came up empty.... It has become a fascination trying to get in touch with him. Hmmm. kind of odd
