Nobody looks this dream up at noon. It arrives at 2am, vivid and specific, and leaves you staring at the ceiling asking one question: does this mean something? The honest answer is yes, but almost never the thing you're afraid it means.
What does it mean to dream about your ex?
Artemidorus, the Golden Wheel and Miller have no entry for "your ex". They catalogued snakes and falling teeth, but not the person you once loved and no longer see, and the books never met yours. The nearest they come is the ending itself: Miller's 1901 dream dictionary (Ten Thousand Dreams Interpreted) has lines on abandoning a sweetheart and on divorce, and those are at the end of this page, reported as what they are.
Everything else here is the modern reading, and it is more consistent than you might expect. Psychologists read the ex less as a person than as a container: for a version of yourself that existed then, for a feeling you had reliable access to, for a lesson that never quite finished teaching itself. They also notice when these dreams come. They cluster at transitions: a new relationship, an anniversary you didn't consciously clock, a move, the end of a job. One ending in a dream can stand in for another.
So the useful question is rarely "do I want them back?" It is closer to "what has just ended, or begun, in my life?"
Getting back together, or not
These are readings from the old dream books, reported as history — no dream foretells the future.
What does it mean to dream of getting back together with your ex?
The reunion dream is the one that sends people to their phone, and it deserves the calmest reading. In the dream everything is easy again, and the waking ache is for that ease. Psychologists hear the dream reaching for what the relationship held, warmth, a younger self, being known, and a reunion is simply the most literal container for it. It is not an instruction, and dreams don't make forecasts.

What does it mean to dream of arguing with your ex?
The fight you never finished, or never had. An argument with an ex in a dream is often that conversation getting a stage at last, the account read aloud so it can be filed. Notice what you were arguing about: the topic is frequently more current than the person, and may belong to a conflict in your life now.

What does it mean to dream your ex is sad?
They look lost, or tearful, or quietly hurt. Many dreamers wake from this one guilty. Psychologists usually hear the dreamer's own feeling worn by the other person: a sadness about the ending that hasn't had room of its own, or a wish that the hurt went both ways. It says nothing about how the real person is doing.
Your ex and other people
What does it mean to dream of your ex with someone new?
The ex walks past with a new partner, and something in your chest drops. This dream tends to arrive when the dreamer is measuring their own progress: who moved on, who didn't, whether it matters. Psychologists hear comparison more than jealousy, and often a rehearsal of letting go, run safely at night before waking life asks for it.

What does it mean when your ex just appears in the background of a dream?
The mildest version, and often the kindest. Your ex simply stands in the crowd: no plot, no charge. Psychologists read this as a matter mostly concluded, still in the archive, no longer on the desk. Many dreamers find this version comes late in healing, and it tends to alarm people far more than it should.
Endings in the old books
What does it mean to dream of breaking up?
Sometimes the dream replays the break-up itself. Miller's "Abandon" entry has the nearest scene: abandoning one's sweetheart, which he read as failing to recover lost valuables and friends turning aside from the dreamer's favours. It is a reading of leaving, not of an ex returning. Psychologists hear the dream going back over the ending to understand it, a normal part of grief for a relationship.
What does it mean to dream of a divorce?
Papers, a lawyer's office, a ring set down. Miller read being divorced in a dream as a sign "that you are not satisfied with your companion, and should cultivate a more congenial atmosphere in the home life"; for women he read it as a single life through the infidelity of lovers. For a dreamer who is already divorced, the modern reading is that the mind is still sorting what the marriage meant.
What does a dream about your ex mean psychologically?
This is an easily misread dream, and the modern correction is steady: dreaming of an ex rarely signals wanting them back. Jung might have said the ex carries a part of the dreamer that was lived through that relationship and not yet fully taken back; the plainer modern reading says the same with less ceremony.
The dream uses the most recognisable face available for a shape that is really about you: something ended, something unfinished, something you're comparing the present to. Which of those it was is usually clear from how you felt on waking, relieved, aching, angry, or oddly calm.
A question to sit with
If the dream wasn't about them, what did that relationship hold that this season of your life is asking about?
The general reading goes only so far, and the old books barely knew this dream at all. Yours has its own shape: an ex who always appears in your first apartment, or only in the weeks before something ends. That part only your own dreams, remembered together, can answer. It's what Dreamlock, on the App Store for iPhone, is built for: it listens to the dreams you record, paints them, and remembers who keeps coming back.
