In my subconscious?

Had a dream abt someone last night. Havent been thinking abt this particular someone for sometime now... and suddenly he just popped into my dream. In that dream, we just got back form a trip somewhere... we're at the airport, wanting to get a cab home.. or sth like that la.. Somehow, this person seemed to be shorter than i am, though in real life, he's not... In that dream, at times i kinda see myself looking at him as a boy, but at times he was also being a very "warm" companion... Hmm... wonder what the interpretations could be... coz the dream was just out of nowhere, no circumstances, no nothing... odd..
