Dream of

I keep dreaming about the same guy I used to attend the same school with even though its not everyday dreams but its been for sometime now its never the same kind of dream but always this same guy when I least expect such dreams , I haven't seen or spoken to him in over 7-8 years now. We were never romantically involved either but the dreams I have now are romantic dreams of me and him, I wish to understand if there is perhaps any meaning behind these dreams or its just because am seeking true love with someone real?
