The mystery of déjà vu, time slips, and higher dimensions
Many of us have experienced that strange, fleeting moment when we pause in the middle of something utterly ordinary, eating, talking to a friend, walking somewhere, and suddenly feel as though everything around us has happened before. The scene looks familiar, the moment feels repeated, and for a few seconds, we are convinced we’ve lived it already. This brief and eerie sensation is known as déjà vu, a French term meaning “already seen.” It lasts only a heartbeat or two, but its impact lingers long after.
To understand why such a feeling arises, people have tried for decades to trace its roots. Some of the most intriguing clues come from unusual events recorded in history, moments when people claimed not just to have seen a familiar moment, but to have slipped into another time altogether. One of the best-known examples occurred in 1901, when two British teachers visited the Palace of Versailles. While strolling through a quiet part of the grounds, they suddenly felt that everything around them had gone unnaturally still. The crowds disappeared, the air thickened, and the atmosphere seemed frozen. When they turned to leave, they found themselves unexpectedly facing people dressed in 18th-century clothing. A woman stood under a tree, laughing as she painted; her appearance strikingly resembled Marie Antoinette. Moments later, a man gestured for them to leave, and when they turned back, the entire vision had vanished. This incident, later named the Moberly–Jourdain Affair, remains one of the most famous “time slip” stories ever told.
But this was not the only such report. In early 20th-century Scotland, a man glanced through a church window and saw people in centuries-old garments praying inside, only for the scene to vanish the moment he stepped through the door. An Italian soldier in 1859 recounted that after being struck during battle, he woke up in a hospital containing lights, machines, and equipment far more advanced than anything known at the time. His diary described a facility that sounded more like a modern hospital than something from the 19th century. A farmer in Ireland once saw Viking warriors charging across his fields with ancient weapons, while in 1981, a Japanese commuter stepped off a subway train only to find himself surrounded by people in medieval clothing and signboards written in ancient Japanese script.
These tales are not confined to the West. Stories from Pakistan and India also mention moments where ordinary people briefly appeared to witness scenes from centuries long gone. A man traveling near the deserts of Thatta once encountered a caravan whose members wore elaborate Mughal-era clothing, their camels loaded with goods, the entire group shimmering behind a faint mist before disappearing altogether. A shepherd in Kashmir claimed to have peeked into a cave and found ancient soldiers asleep with their weapons, a tale that became local legend. A British officer in colonial Delhi wrote in his diary that while riding through a market, he suddenly saw scenes resembling the Mughal era, soldiers, merchants, and women riding elephants, only for everything to return to normal with a blink.
These stories are anecdotal, of course, collected from diaries, interviews, and folklore. But they all point towards the same mystery: fleeting glimpses of another era, as if the border between two moments in time momentarily thinned.
Alongside these sightings, puzzling physical objects have also been discovered, items found in places and times where they seemingly do not belong. Archaeologists have labelled them OOPArts, or “Out of Place Artefacts.” Among the most famous is the Antikythera Mechanism, a complex device more than 2,000 years old that functions like an ancient analogue computer. Considering the technological capabilities of its era, its existence is astonishing. No other mechanism from that time demonstrates such sophistication.
In Colombia, gold figurines more than a thousand years old were unearthed, tiny models shaped uncannily like modern aeroplanes with aerodynamic wings. A hammer discovered inside a rock millions of years old, known as the London Hammer, contained nearly pure iron, a level of refinement impossible for that prehistoric period. Iraq’s Baghdad Battery suggests people may have created a form of electrical device two millennia ago. Even more baffling are stones in Egypt and India drilled with machine-like precision, and aluminium tools discovered in Romania, despite the fact that aluminium, historically, could not be produced without electricity.
All of this leads to bigger questions, not just about artefacts or historical glitches, but about time itself. For centuries, people believed time moved in a straight line: the past behind us, the future ahead. But Einstein shattered that certainty when he showed that time can stretch, shrink, and warp. The Qur’an, interestingly, aligns with this idea. It reminds us repeatedly that time on Earth is not the same as time with Allah; one day in His sight can equal a thousand years or even fifty thousand years for us.
Einstein’s revolution paved the way for others to rethink time entirely. Erwin Schrödinger, one of the 20th century’s greatest scientists, once stated that reality may not consist of a single timeline but several, running side by side. From such ideas emerged the Block Universe Theory, the notion that past, present, and future all exist simultaneously, like pages in a book. We, as conscious beings, perceive one page at a time, but the entire “book” is already there. If somehow we momentarily glimpse another page, we feel déjà vu. If the veil thins enough for a full scene to appear, we witness what people call a time slip.
This concept echoes metaphysical ideas found in many traditions. The Qur’an speaks of a Preserved Tablet containing everything that has ever happened and will ever happen, a timeless record. It tells us Allah knows “what is before them and what is behind them,” hinting that all events across history exist in His knowledge at once. In a sense, that is what the Block Universe attempts to express through physics and mathematics, though it lacks the spiritual dimension.
As our understanding deepens, we encounter ideas even more complex, such as the existence of higher dimensions. For centuries, humanity understood only three dimensions: length, width, and height. Einstein added time as a fourth. Later, mathematicians realised that their equations only worked correctly if the universe had ten dimensions. Anything fewer or more broke the calculations, as though the universe itself were a lock that could only be opened with a key containing exactly the right number of teeth.
In these higher dimensions, the flow of time would not match ours. Creatures like angels or jinn, beings described in the Qur’an as operating on a different timeline, may move through these dimensions in ways impossible for us to comprehend. Their “time blocks,” so to speak, would differ completely from ours.
All these theories, discoveries, and mysteries point toward a universe far more complex than our everyday experience suggests. Perhaps when someone experiences déjà vu, their consciousness briefly glances at another frame in the cosmic film reel. Perhaps time slips are glitches in our perception, revealing hidden layers of reality. Or perhaps they are reminders that the universe operates on dimensions and rules beyond the reach of ordinary senses.
Whatever the explanation, these moments, fleeting, strange, unforgettable, continue to inspire wonder. They challenge our assumptions, push us to rethink the nature of existence, and remind us that the world is far more mysterious than it appears in the passing moments we call “time.”
