Can Dreams Predict the Future? What Science and Faith Say

You dream about an old friend you have not thought of in years, and the next morning their name lights up your phone. Or the dream is darker: a crash, a flood, a funeral, and days later the news delivers something uncomfortably close. Few experiences feel more uncanny, and few questions about dreaming are older. Can a dream show you the future before it happens?

People have answered that question with temples, prophets, government filing cabinets and blockbuster films. This guide walks through all of it: the schoolgirl whose dream preceded one of Britain's worst disasters and the strange official experiment it inspired, the famous premonitions of Lincoln, Twain, the Titanic and Jung, what the mathematics of coincidence and modern sleep science actually say, the one case where medicine agrees a dream can warn you years in advance, how Islam, the Bible and cultures around the world understand prophetic dreams, the best films built on the idea, and a simple, honest test you can run on your own dreams starting tonight.

The Dream Before Aberfan

On 20 October 1966, in the Welsh mining village of Aberfan, a ten-year-old girl named Eryl Mai Jones told her mother about a dream she had just had:

I dreamt I went to school and there was no school there. Something black had come down all over it.

The next morning, a colliery waste tip on the hillside above the village gave way. A dark wave of coal slurry slid down the slope and buried Pantglas Junior School. 144 people were killed, 116 of them children. Eryl Mai was one of them. In the weeks that followed, a psychiatrist named John Barker visited Aberfan. He was interested in whether disasters cast shadows ahead of themselves, and with the help of a London newspaper he issued a public appeal: had anyone sensed or dreamed the disaster before it happened? Seventy-six replies came in. Most could not be checked. But a handful, including Eryl Mai's dream, had been described to somebody else before the tip came down, and Barker found those hard to dismiss.

What happened next sounds like fiction, and it is one of the strangest true stories in the history of dreaming. In 1967 Barker and science journalist Peter Fairley set up the British Premonitions Bureau, a standing office where members of the public could log their dreams and forebodings the moment they had them, so that any later match could be verified against a dated record instead of an improving memory. A year later a copy opened in New York, the Central Premonitions Registry, run by Robert Nelson. For a few years, two cities on either side of the Atlantic quietly operated something close to an early warning system powered by dreams.

The results are the most instructive part. The London bureau logged around a thousand premonitions in its first eighteen months. The overwhelming majority matched nothing at all, and not a single disaster was ever prevented. A small number of contributors did seem to score again and again, and the strangest twist belongs to them: as Sam Knight recounts in his history The Premonitions Bureau, the office's two most reliable correspondents both warned that Barker himself would die soon, and in 1968, at the age of 44, Barker died of a brain haemorrhage. The bureaus faded within a few years, leaving behind exactly the question they were built to answer. Were the hits glimpses of the future, or the statistical residue of a thousand misses that nobody counted?

Famous Dreams History Keeps Retelling

In the spring of 1865, Abraham Lincoln reportedly described a dream to his wife and a small circle of friends that included his bodyguard, Ward Hill Lamon. In the dream, the White House was filled with the sound of weeping. Wandering the rooms to find its source, Lincoln entered the East Room and found a coffin resting on a platform, guarded by soldiers, surrounded by mourners.

'Who is dead in the White House?' I demanded of one of the soldiers. 'The President,' was his answer; 'he was killed by an assassin.'

Days later, Lincoln was assassinated, and the dream became perhaps the most quoted premonition in history. It deserves its honest footnote: the only source is Lamon's memoir, published thirty years after that evening, and nobody wrote the dream down at the time. That does not make the story false. It makes it unverifiable, and that, as we will see, is the problem with almost every famous prophetic dream.

Mark Twain told an even stranger one. In 1858, as young Samuel Clemens, he was working the Mississippi steamboats alongside his beloved younger brother Henry. One night he dreamed he saw Henry's body laid out in a metal coffin resting on two chairs, with a bouquet of white flowers on his chest and a single crimson bloom at its centre. Weeks later, the boilers of the steamboat Pennsylvania exploded near Memphis, and Henry died of his injuries. When Samuel reached the room where the dead lay, he found his brother in a metal coffin resting on two chairs. The other victims lay in plain wooden ones; the people of Memphis had raised money for something finer for the well-liked young clerk. As he stood there, an elderly woman stepped forward and laid a bouquet of white flowers on Henry's chest, a single red rose at its centre. Twain retold that dream for the rest of his life. Yet it was first published only after his death, in his official 1912 biography, and half a century of retelling is a long time for a memory to sharpen its own details.

The Titanic left behind at least one premonition with unusually good paperwork. J. Connon Middleton, a London businessman booked on the maiden voyage, dreamed two nights running of a great ship 'floating on the sea, keel upward, and her passengers and crew swimming around her'. Crucially, he described the dream to his wife and friends before the ship sailed, and those witnesses later confirmed it. The honest footnote here cuts the other way: Middleton did not cancel because of the dream. A business conference in New York was postponed, and he gave up his ticket four days before departure for entirely mundane reasons. When the researcher Ian Stevenson combed through claimed Titanic premonitions half a century later for the Journal of the American Society for Psychical Research, Middleton's case stood among the very few corroborated before the event, in an ocean of stories told only afterwards.

Even the great psychologists were not spared. In October 1913, Carl Jung was overwhelmed, twice, by a waking vision of a monstrous flood covering Europe, its waters turning to blood. Through the spring of 1914 he dreamed three times of the continent frozen dead under Arctic ice in the middle of summer. Jung privately feared he was losing his mind. When the First World War broke out that August, he drew a different conclusion: that the psyche can sense a gathering storm in the collective mood long before events arrive. Notably, he did not read his visions as literal prophecy, but as evidence of how deep the mind's antennae reach. Both experiences are described in his memoir, Memories, Dreams, Reflections.

What Science Actually Says

Begin with the arithmetic, because it dissolves most of the mystery on its own. Statisticians Persi Diaconis and Frederick Mosteller named the principle the law of truly large numbers: with a large enough sample, any outrageous coincidence becomes not just possible but expected. The sample here is enormous. Eight billion people dream several times every night, which adds up to tens of billions of dream scenes per day. If a dream matching the next day's events were literally a one in a million occurrence, it would still happen tens of thousands of times every single night, somewhere on Earth. The people it happens to will remember it forever and tell the story for years. The billions of dreams that matched nothing are never counted, because there is nothing to tell.

Memory then quietly improves the story. We recall dreams selectively, keeping the eerie hits and dropping the misses, and dreams are vague enough that a single image can be matched to many different later events. Worse, a dream retold after the event tends to absorb the event's details, which is exactly why the Lincoln and Twain stories, both first written down decades later, are so hard to evaluate. When people are asked to record dreams with a date stamp first and check for matches afterwards, dramatic hit rates deflate sharply toward what chance predicts. The dream did not change. The bookkeeping did.

Science has given precognition its fair shot, and the result became famous for a different reason. In 2011, Cornell psychologist Daryl Bem published Feeling the Future in a leading journal: nine experiments that appeared to show people's responses being influenced by events that had not yet happened. The methods looked completely standard, and that was precisely the problem. When other researchers repeated the experiments, the effects vanished; a high-profile failed replication by Stuart Ritchie, Richard Wiseman and Christopher French found nothing, and the episode helped trigger what psychology now calls its replication crisis, a wholesale reckoning with how easily standard methods can manufacture positive results. It remains the field's clearest verdict: under conditions that rule out coincidence and hindsight, evidence that minds sample the future has not held up.

When Dreams Really Do Know Something First

And yet medicine keeps one genuinely predictive dream phenomenon on its books. In REM sleep behaviour disorder, the body's normal dream-time paralysis fails, and sleepers begin to physically act out their dreams: punching, shouting, leaping from bed, often inside dreams of being attacked or chased. Long-term studies have shown something remarkable and sobering. This change in dreaming often precedes Parkinson's disease and related conditions by years, sometimes decades, and a large majority of people with the disorder eventually develop one of them. A dream, or at least a change in how dreams are performed, really can be one of the earliest warnings the brain sends. Anyone who regularly acts out violent dreams should mention it to a doctor, not a fortune teller.

Milder versions of the same principle are uncontroversial. The dreaming brain has quiet access to the body's early signals, and an illness still below the threshold of daytime notice can colour dream content days before symptoms declare themselves. The observation is ancient: Aristotle wrote a short treatise called On Divination in Sleep and arrived, more than two thousand years early, at roughly the modern answer. Most prophetic dreams are coincidence, some reveal the body's first whispers of illness, and some come true because the dreamer, having dreamed, behaves differently and makes them come true.

Modern dream science then goes one step further, in a direction stranger than prophecy: dreaming may exist in order to deal with the future. The threat simulation theory of Finnish neuroscientist Antti Revonsuo proposes that dreams evolved as a nightly rehearsal space, where the brain runs simulations of dangers so that we handle them better awake, which fits the huge overrepresentation of chases, falls and threats in dreams worldwide. Newer memory research paints dreaming as the brain's simulation engine more broadly, recombining past experience to model what might come next: the exam, the interview, the difficult conversation. On this view, your dreams genuinely are about the future every single night. They are forecasts rather than prophecies, built from your worries, your patterns and your body's signals, and they 'come true' most often when they simply knew you well.

What Faith Traditions Teach

Long before statistics existed, faith traditions built careful frameworks for exactly this question, and most are more nuanced than a simple yes. In Islam, true dreams hold real standing: a well-known hadith calls the righteous believer's true dream one of the forty-six parts of prophethood, and tradition teaches that revelation to the Prophet Muhammad began with dreams that came true like the light of morning. At the same time, Islamic scholarship divides dreams into three kinds, from Allah, from Satan and from the self, and holds that most dreams belong to the last group, which is why interpretation calls for knowledge and restraint rather than alarm. We cover the whole teaching, from what makes a dream a ruya sadiqa to the etiquette after a nightmare, in our guide to true dreams in Islam.

The Bible tells its history through dreamers: Joseph reading Pharaoh's seven fat and seven lean cows as fourteen years of feast and famine, Daniel interpreting the troubled dreams of kings in Babylon, another Joseph warned in a dream to take his family and flee to Egypt, and the Magi warned not to return to Herod. Scripture treats dreams as one of the ways God has spoken, while also warning sharply against false dreamers and diviners. The prophet Joel promised dreams a place in the future itself:

And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions.

Joel 2:28 (King James Version)

You can read the full story in our guide to dreams in the Bible. And step outside the Abrahamic world and the conviction that dreams touch the future is close to universal: an Egyptian prince napping in the shade of the Sphinx, Greek pilgrims sleeping in temples to receive healing dreams, Lakota vision seekers fasting on a hill, Japan's lucky first dream of the year. That world tour deserves its own article, and it has one: prophetic dreams across cultures.

Many modern spiritual readers follow Jung. A dream that comes true is a synchronicity, a meaningful coincidence, and its value lies in what it reveals about you rather than in any power to predict. On this reading, the dream's job is preparation, not prophecy: it turns your attention toward something your deeper mind already considers urgent, and the later event simply proves the concern was real. If you want to explore what a striking dream means rather than what it predicts, our overview of dream interpretation methods compares eleven ways of doing it.

Prophetic Dreams in Movies and Books

The modern fascination has a specific father, and he was an aircraft engineer. In 1927, J. W. Dunne, one of Britain's pioneering aeroplane designers, published An Experiment with Time, in which he claimed his dreams regularly previewed small details of his own future and proposed both a theory (that all moments exist together, with the dreaming mind free to wander forward) and a method: keep a dated dream journal and check it against your life. The book became a bestseller that taught a generation to write down its dreams, and its fingerprints are all over time-slip fiction, from J. B. Priestley's time plays to unpublished experiments by J. R. R. Tolkien.

Cinema has been running the thought experiment ever since. Minority Report imagines precognition industrialised, with 'precogs' whose visions convict people of crimes not yet committed, and asks whether a foreseen future can be refused. Dune gives its hero prescient dreams as a burden and a trap: seeing the path makes it nearly impossible to step off it. Premonition and The Dead Zone play out the tragedy of knowing without being believed, and the Final Destination films turned the warning vision into horror's most efficient engine. Arrival, the closest in spirit to Dunne, imagines a mind that experiences time all at once, and Twelve Monkeys hides the ending of a life inside a recurring dream its owner cannot yet place.

The furthest anyone has pushed the idea is Ursula K. Le Guin's novel The Lathe of Heaven, about a man whose dreams do not predict reality but quietly replace it, so that each morning the world has always been the way he dreamed it. All of these stories dramatise the paradox the real premonitions bureaus ran into: a future you can see but cannot use is a haunting, and a future you can change was never fixed in the first place.

The Only Honest Test: Your Own Dream Journal

Here is the good news: this is one of the few big questions about dreams you can investigate yourself, with essentially the protocol Dunne proposed a century ago. Everything depends on one rule. The dream must be written down before the world has a chance to imitate it.

1. Record the dream the moment you wake, with the date and time. A premonition that exists only in memory is evidence of nothing.
2. Be specific. Names, places, numbers, details. Vague dreams match everything and therefore prove nothing.
3. Never edit an entry afterwards. The dated original is the whole experiment.
4. Review weekly and monthly, and score honestly. Count the misses with the same enthusiasm as the hits.
5. Decide in advance what would count as a match. If the rules are written after the event, the event is writing the rules.

Run this for three months and you will almost certainly discover what dated records always show: fewer miracles than memory promised, and far more insight. The journal fails as a crystal ball and succeeds as something better, a record of what your mind keeps rehearsing, worrying over and preparing you for. If you rarely remember your dreams at all, start with our guide to remembering your dreams. And this is exactly what Ruya was built for: a private dream journal with dated entries, so your record exists before the coincidence does, and interpretation tools for when a dream deserves a closer look.

What To Do When a Dream Comes True

First, breathe. Given the arithmetic above, a dream that matches reality is something that happens to most people a few times in a life, and it arrives with a powerful feeling of significance that is real as a feeling but not as proof. Write down exactly what you dreamed and exactly what happened, while both are fresh; the differences you notice are usually revealing. Do not make major decisions on the strength of a dream alone, and do not let a dream of death or disaster frighten you: such dreams are among the most common of all and overwhelmingly reflect stress and change rather than events to come. If the same ominous dream keeps returning, that is a pattern worth understanding, and our guide to recurring dreams explains what keeps a dream on repeat. A dream that came true is, above all, a dream worth interpreting, because whatever else it did, it showed you what your mind considers important.

So, can dreams predict the future? Not in the way the premonitions bureaus hoped, and every dated record we have says the miracles thin out once the bookkeeping begins. But your dreams are forecasting machines all the same: rehearsing threats, surfacing the body's first signals, staging the decisions you have not admitted you are making. Sometimes they will be right. The interesting question is never only whether a dream came true, but why your mind chose that story on that night, and that question has an answer you can actually find. Write them down, date them, and read them back. The future is a long shot. Yourself, you can predict.
