What does dreaming about someone mean? Almost always something about you rather than a message from them, because the person in your dream was assembled entirely out of your own memory of them. That is a less romantic answer than the usual one and a considerably more useful one, since it tells you what your mind is currently doing with that person, and that is something you can work with.
It is fair to ask whether it can ever be more than that. Here is what can honestly be said about it.
Does dreaming about someone mean they are thinking about you?
There is no way to check, and it has never been shown to be true. Plenty of people believe it, some of them on the strength of an experience nobody could talk them out of, and we are not going to be snide about that.
What can be said plainly is this: a dream about someone is not evidence that they are thinking of you, and it is not a sign that they are about to get in touch. If you have been waiting on a message from a particular person and then you dream about them, the simpler explanation is that you have been thinking about them all week and your sleeping mind carried on the same thread it had been running all day.
The better version of the question is the one sitting underneath it. What is the waiting costing you?

The person in the dream is your version of them
Whoever turned up, you built them. Their face, their voice, the way they treated you in the dream, all of it came out of your own material.
That is why a dream can hand you a warm conversation with someone who has never once been warm to you, or a cutting remark from a person who has never been cruel in their life. The dream is not reporting on their character. It is showing you how you are currently holding them: what you wish they had said, what you are braced for, what you have not finished feeling about them.
So the question is never what does it mean that I dreamed about him. It is what part of me is that version of him carrying.
Who tends to show up, and what it usually tracks
- An ex. Extremely common, including many years later, including people you are glad to be rid of.
- A parent or grandparent. Often arrives when you are facing a decision they would have had an opinion about.
- A colleague or a boss. Almost always about the situation rather than the person. These dreams tend to be dull and repetitive, which is a clue in itself.
- A friend you have drifted away from. Frequently shows up alongside a change in your current friendships.
- Someone you barely know. Usually a face borrowed to play a part. The person is set dressing.
- A public figure. Generally standing in for a quality or a position you have been chewing over.
Dreaming about an ex years after it ended
This causes more distress than almost any other dream about a person, and less of that distress is warranted than people think.
Dreaming about an ex does not mean you are secretly still in love with them and it does not mean you made the wrong call. A long relationship is attached to entire years of your life, so the person ends up working as a convenient index for that whole period. Dream about them at thirty-eight and the subject is often not the relationship at all. It is who you were at twenty-six.
Look at what the dream had you doing rather than who you were doing it with. A dream where you are back in an old flat arguing about nothing is usually about the feeling of being stuck. A dream where the two of you are friendly and it is unremarkable tends to show up after something has genuinely settled, sometimes before you have noticed that it has.

Dreaming about someone who has died
These are common, and they are often the dreams people value most. They can also be the hardest.
The plain description is that grief keeps a person present in your mind, and sleep gives that presence room to move around. Some of these dreams are ordinary and warm: a kitchen, a conversation, nothing dramatic, and you wake up glad. Some are painful, particularly the ones where the person does not seem to know they have died, or the ones where you cannot reach them or make them hear you.
Whether such a dream is a visit is not something anyone can settle for you, and we are not going to pretend we can. What we would say is that the comfort many people take from these dreams is not something to argue with, and the distress other people feel afterward is not a sign that anything has gone wrong with their grieving.
If grief is sitting heavily on you, a grief counselor or your doctor is the right place to take that weight, alongside anything else you do.
When the dream is uncomfortable and the person is someone ordinary
Sexual dreams about colleagues, dreams where you are cruel to a friend, dreams where you are relieved that something bad happened to someone: people carry these around feeling ashamed and rarely say them out loud.
They are extremely common and they are not confessions. A dream is not a wish and it is not a plan. It borrows whoever is available and puts them in whatever scene it is working on, and proximity is often the only reason a particular person got cast. The person you see for eight hours a day is simply the nearest face to hand.
If a dream like that leaves you uneasy, the question worth asking is about the feeling, not the casting. Where else does that shame or that relief show up in your week?
When you wake up wanting to message them
Wait a day. Not because the impulse is bad, but because it is at its least accurate in the first hour after waking.
If you still want to reach out tomorrow, reach out as yourself, on the strength of what you actually want, and leave the dream out of the message. "I dreamed about you" puts a strange weight on the other person and usually produces an awkward reply. "I have been thinking about you" is true, is simpler, and is the thing you meant anyway.
If you do not want to contact them and the dream will not leave you alone, write them a letter you never send. It sounds like a cliche because it works.
Is this the same for everyone?
No. The patterns here are the common ones, and yours may sit somewhere else entirely. Treat any general answer as a starting point to react against rather than a verdict, and pay more attention to where it does not fit you than where it does.
Where should I take this next?
If it keeps coming back, or you would like a second read on your particular version of it, that is worth a conversation with somebody rather than another search. Anything that is genuinely distressing belongs with a professional.

If you want your own dream looked at properly
Dreams about people hold a lot of detail that a general article cannot reach. What they were wearing. Whether you spoke or whether the whole thing was silent. Whether the room was somewhere you know. Whether you woke up relieved or hollow.
The Dream Interpretation Reading is a written piece from one of our advisors about your dream specifically, back with you within a day. You describe it in your own words, at whatever length it takes, and what comes back is written for your dream and the person in it rather than a general rule laid over your life.
It earns its place when a dream about someone has stayed with you for days, or when it keeps returning and you would like a second pair of eyes on what it might be circling.
