It means you subconsciously miss your relationship with that person, and guess who gets to rule over the majority of your dream state? . . . Your subconscious, so of course things you keep tucked down deep will surface during your dream state.
I had a dream in which I became friends with someone that I (used to) have a LOT of admiration for, even though we haven't spoken since, probably, close to a year ago now ( :[ ) what does it mean?
Nothing. Dreams are totally random access of stored memory in your subconcious played like a movie in your unconscious imagination. Totally. Random. Things from years ago can pop up in a dream often for no reason. It doesnt mean anything.
