What does it mean when you continue to dream of someone from your past you haven't seen or talked to in a very long time and in the dreams you meet up with this person in really random scenarios?
That's why he or she is the one haunting you. They usually go away after Halloween but you never know.
It may mean nothing, amigo. There is no scientifically supported system of dream interpretation. There are a ton of web sites offering "dream dictionaries" but they mostly peddle nonsense along the lines of new age “spiritualities” and ideologies. And some are simple charlatan soothsayers. Occasionally you will get a scientist with some track record in dream research offering his or her idiosyncratic interpretation of a dream or two. Some have studied dreams and post “interpretations” of common dream themes but they know full well that there are no data to support any particular interpretative scheme over another. Ultimately your dreams are based on your own psyche and only you can figure out what they mean, if they mean anything at all. Many dreams may simply be your brain having some mindless entertainment.
red is mostly right but dreams can and do at time, reflect your subconscious, reflect your fears, joys, desires, and stresses, allow you to deal with things that your conscious doesn't want to. In your case, something might have triggered your memory of this person and your curiosity of a potential meeting or it could be simply representative of something you need to take care of, but haven't. Or none of those and you are paranoid.
There might be something to it. A woman who worked in the same place I did had a dream book and she would buy pick 3 and pick 4 lottery tickets according to the book's interpretation of her dreams. She won pretty often
