Your Consciousness Can Enter Alternate Dimensions While You’re Dreaming, Scientist Claims

Strong emotions in repetitive dreams could offer cosmic clues about another version of you, according to this controversial idea. By Stav DimitropoulosPublished: Oct 18, 2024 12:52 PM EDT

How many times have you woken up feeling euphoric or deeply disturbed by a dream so vivid it felt indistinguishable from reality? The kind of dream that lingers. Perhaps you notice recurring motifs: specific places, faces, symbols, or even fantastical settings. You are quick to dismiss these as psychological quirks of the brain, and chances are, you will have forgotten about such dreams by midday.

But what if your dreams weren’t just caprices of the sleepy mind? What if they were revealing glimpses into a mirror realm in which your consciousness was wandering? To go even further, perhaps recurring dreams suggest a connection to another reality. For David Leong, Ph.D., an academic specializing in metaphysics and epistemology (the study of distinguishing opinion from justified belief) this might not be just an interesting hypothesis, but the truth.

“Dreams may be windows into distinct realities governed by their laws, in which the mind, unfettered by the constraints of wakefulness, can explore and interact with new forms of existence,” says Leong, an honorary professor at Charisma University in Turks and Caicos.

His hypothesis builds on the Many Worlds interpretation of quantum theory, which suggests that every decision or event creates branching realities—an infinite array of parallel universes. Leong applies this idea to consciousness. He speculates that sleep reduces the influence of our physical senses and rational mind, giving consciousness the freedom to bypass the usual boundaries of time and space. While scientific studies don’t currently support this idea, in Leong’s view, dreams might serve as portals to other versions of ourselves existing in other dimensions.

“AT THE MACROSCOPIC LEVEL, WE ASSUME objects have fixed properties like position or velocity. But quantum experiments challenge this assumption,” Leong explains. The observer effect—where simply observing a quantum system can influence its state—shows that reality is far more fluid than it appears. “Seeing is believing” might hold true in our everyday world, suggests Leong, but at the quantum level, it breaks down, likely shifting according to the observer’s interaction.

In 2022, physicists Alain Aspect, John F. Clauser, and Anton Zeilinger won the Nobel Prize for their groundbreaking work on quantum entanglement. Their experiments challenged the classical notion of local realism—the belief that physical properties exist independently of observation. They demonstrated that particles, even when separated by vast distances, could instantly affect each other. This fact suggests a reality far more interconnected and flexible than scientists previously thought.

Building on their research, Leong explores the concept of “local” and “nonlocal” consciousness. Local consciousness is accountable to our five senses, shaped and sculpted by the body’s sensory input. Nonlocal consciousness, however, transcends the senses, allowing us to experience “broader, interwoven realities,” he says. This concept aligns with speculative ideas such as panpsychism, where awareness is considered a fundamental feature of the universe itself, he says.

Fascinating as this may sound, not all dreams serve as gateways to parallel timelines. Whether dreams return is key here. “Recurring dreams, especially those with vivid and consistent scenarios, might suggest deeper connections to other realities,” Leong claims. On the other hand, dreams tied to personal experiences often feel disjointed, with distorted time. The most surreal and incomprehensible dreams are likely the subconscious processing your life here on Earth, he says. But, if it feels like you’re visiting the dream rather than imagining it—like a play with a beginning, middle, and end—you probably are visiting this other world, under Leong’s hypothesis.

Leong also hints that strong emotions in persistent dreams could offer cosmic clues—signals of how another version of you is experiencing life in a parallel world. “Say you have a repetitive dream of being stuck in high school,” he suggests. “While it may reflect unresolved psychological themes, such as feelings of stagnation or anxiety about personal growth, it could also indicate that in another reality, you are still in high school, dealing with the same challenges your waking self has moved beyond.” This emotional resonance—like the frustration of being stuck—could ripple across dimensions, creating a feedback loop between your conscious mind here and one of your alter egos elsewhere.

YET, AS CAPTIVATING AS THIS HYPOTHESIS MIGHT BE, it runs into a significant problem: there’s no empirical evidence to back it up. Quantum phenomena, such as entanglement and nonlocality, challenge our traditional views on time and space. Yet, no scientific studies conclusively support the idea that dreams are portals to other worlds. Mainstream neuroscience and cognitive science, on the other hand, find this hypothesis heretical—if not downright unscientific.

The activation-synthesis theory, for instance, sees dreams as the brain’s attempt to make sense of random neural activity during the rapid eye movement (REM) stage of sleep. It’s the time when the brain is highly active, colorful dreams occur, and the body experiences temporary muscle paralysis. There’s no evidence of peering into other dimensions whatsoever. Similarly, the memory consolidation theory frames dreams as a tool for organizing daily experiences into long-term memories—not interactions with different selves. The threat simulation theory says dreams serve a survivalist, biological purpose, helping us practice responses to danger—again, there’s no cosmic link.

In addition, almost all of the most prominent schools of modern psychology steer away from metaphysical explanations. Behaviorism, for example, regards dreams as byproducts of learned behaviors, conditioning, or stimuli experienced during waking life, offering no deeper meaning. Some psychologists say dreams are expressions of unresolved conflicts or unintegrated parts of the self. Even the more “liberal” psychoanalysts remain focused on the personal meanings of dreams. Sigmund Freud viewed dreams as the “royal road to the unconscious,” reflecting hidden desires and conflicts. Carl Jung offered a more metaphysical take by proposing that dreams connect us to a collective repository of archetypal experiences shared by all humans. However, he never implied that dreams were gateways to other realities.

Psychologist and physician Dr. Howard Eisenberg explores the intersection of psychology, quantum physics, and consciousness in his book, Dream It to Do It. He suggests that what we perceive as reality might be a collective illusion fueled by Western academia’s blind faith in empirical observation. Generally aligned with Leong’s thinking, Eisenberg argues that perception itself may be responsible for constructing the solidity of our reality.

His argument borrows from the observer effect, which says that observing the world around us is a process that collapses potential realities into one fixed outcome. “In modern quantum mechanics, we no longer view objects as collections of particles but rather as ‘waves of probability,’” Dr. Eisenberg says. There are no physical building blocks, no inherent solidity. Simply put, we—all of us together—created the solids we perceive.

“As strange as this may seem, we are the ones caught in a dreamlike state,” Eisenberg adds.

Our Consciousness May Come From a Higher Dimension

This Study Backs a Quantum Theory of Consciousness

If dreams truly are doorways to other worlds, they would change the way we live. “Every time you sleep, you wouldn’t just rest—you’d explore. You’d live out alternate versions of yourself, making choices that branch into countless realities,” Leong says. Time would blur across the past, present, and future and across dimensions. Death, too, might lose its finality: “Perhaps you wouldn’t see it as the end, but a transition—another path into a new reality, where consciousness continues to evolve,” he explains.

By logical progression, life itself would feel richer, like a dynamic puzzle of possibilities, pushing us to take risks, explore new paths, and live with the understanding that actions shape not just this life, but infinite versions of ourselves across many realities. Each decision or event could unfold into a fresh act in the ongoing narrative of you. And if one bold or misguided move leads to catastrophe here—well, there would still be countless other dreams to live.

Meccanica quantistica fuori dall'Universo localmente reale

L’universo non è localmente reale. È ciò che hanno provato i vincitori del premio Nobel per la Fisica del 2022 in seguito a esperimenti di correlazione quantistica tra fotoni. A quanto pare, l’universo non è localmente reale. A rivelarlo sono stati i vincitori del premio Nobel per la Fisica del 2022, Alain Aspect, John F. Clauser e Anton Zeilinger. Ma cosa vuol dire “localmente reale”? Si dice ‘reale’ quando gli oggetti hanno proprietà indipendenti dall’osservazione: per esempio, una mela può essere rossa anche quando nessuno la sta guardando. Mentre ‘locale’ significa che gli oggetti possono essere influenzati solo dall’ambiente circostante e, in particolare, che qualsiasi influenza non può viaggiare con una velocità superiore a quella della luce nel vuoto. Ciò che è stato scoperto è che l’universo non può essere locale e, forse, nemmeno reale. Un apparente paradosso della meccanica quantistica Un famoso esperimento mentale pubblicato nel 1935, il cosiddetto paradosso di Albert Einstein, Boris Podolsky e Nathan Rosen (paradosso EPR), era inteso a illustrare la presunta assurdità della meccanica quantistica. Il loro obiettivo era mostrare come in determinate condizioni la teoria può fornire risultati privi di senso.

Niklas Elmehed, Nobel Prize Outreach/a." width="678" height="381" /> Ritratto, in ordine da sinistra a destra, di Alain Aspect, John F. Clauser e Anton Zeilinger, vincitori del premio Nobel per la Fisica nel 2022. Crediti: Niklas Elmehed, Nobel Prize Outreach. Una versione semplificata e modernizzata di EPR funziona più o meno così: abbiamo delle coppie di particelle che vengono espulse in direzioni diverse da una stessa sorgente e raggiungono due osservatori, Alice e Bob, posizionati alle estremità opposte del sistema solare. La meccanica quantistica impone che sia impossibile conoscere lo spin, una proprietà quantistica di ciascuna particella, prima della misurazione. Una volta che Alice ha misurato una delle sue particelle, trova che lo spin risulta up oppure down. I suoi risultati sono casuali, eppure appena dopo aver effettuato la misura, sa immediatamente che la particella corrispondente di Bob deve avere spin, per esempio, down. Eppure lo spin di quest’ultima particella era indefinito prima che fosse misurato lo spin dell’altra. Se le particelle di Alice non hanno uno spin definito prima della misurazione, allora come fanno le particelle di Bob, dall’altra parte del sistema solare, a ‘sapere’ che la misura è stata effettuata e il suo risultato? Nonostante i miliardi di chilometri che separano le particelle accoppiate, la meccanica quantistica prevede che le particelle di Alice sono in qualche modo legate a quelle di Bob (un fenomeno noto come entanglement quantistico). I tre scienziati premiati sono riusciti a studiare fotoni in stato di entanglement. Secondo la meccanica quantistica, quindi, la natura non è localmente reale: le particelle possono avere proprietà indefinite prima della misurazione, come lo spin up o down, e influenzarsi istantaneamente tra loro a prescindere dalla distanza. Ciò però non viola i risultati della teoria della relatività ristretta, in quanto i risultati delle misurazioni sono casuali e quindi l’entanglement non possono essere utilizzate per comunicare a velocità superiore a quella della luce nel vuoto.

LHC experiments at CERN observe quantum entanglement at the highest energy yet

LHC experiments at CERN observe quantum entanglement at the highest energy yet Quantum entanglement is a fascinating feature of quantum physics – the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bending phenomenon, which has no analogue in classical physics, has been observed in a wide variety of systems and has found several important applications, such as quantum cryptography and quantum computing. In 2022, the Nobel Prize in Physics was awarded to Alain Aspect, John F. Clauser and Anton Zeilinger for groundbreaking experiments with entangled photons. These experiments confirmed the predictions for the manifestation of entanglement made by the late CERN theorist John Bell and pioneered quantum information science. Entanglement has remained largely unexplored at the high energies accessible at particle colliders such as the Large Hadron Collider (LHC). In an article published today in Nature, the ATLAS collaboration reports how it succeeded in observing quantum entanglement at the LHC for the first time, between fundamental particles called top quarks and at the highest energies yet. First reported by ATLAS in September 2023 and since confirmed by two observations made by the CMS collaboration, this result has opened up a new perspective on the complex world of quantum physics. "While particle physics is deeply rooted in quantum mechanics, the observation of quantum entanglement in a new particle system and at much higher energy than previously possible is remarkable,” says ATLAS spokesperson Andreas Hoecker. “It paves the way for new investigations into this fascinating phenomenon, opening up a rich menu of exploration as our data samples continue to grow." The ATLAS and CMS teams observed quantum entanglement between a top quark and its antimatter counterpart. The observations are based on a recently proposed method to use pairs of top quarks produced at the LHC as a new system to study entanglement. The top quark is the heaviest known fundamental particle. It normally decays into other particles before it has time to combine with other quarks, transferring its spin and other quantum traits to its decay particles. Physicists observe and use these decay products to infer the top quark’s spin orientation. To observe entanglement between top quarks, the ATLAS and CMS collaborations selected pairs of top quarks from data from proton–proton collisions that took place at an energy of 13 teraelectronvolts during the second run of the LHC, between 2015 and 2018. In particular, they looked for pairs in which the two quarks are simultaneously produced with low particle momentum relative to each other. This is where the spins of the two quarks are expected to be strongly entangled. The existence and degree of spin entanglement can be inferred from the angle between the directions in which the electrically charged decay products of the two quarks are emitted. By measuring these angular separations and correcting for experimental effects that could alter the measured values, the ATLAS and CMS teams each observed spin entanglement between top quarks with a statistical significance larger than five standard deviations. In its second study, the CMS collaboration also looked for pairs of top quarks in which the two quarks are simultaneously produced with high momentum relative to each other. In this domain, for a large fraction of top quark pairs, the relative positions and times of the two top quark decays are predicted to be such that classical exchange of information by particles traveling at no more than the speed of light is excluded, and CMS observed spin entanglement between top quarks also in this case. “With measurements of entanglement and other quantum concepts in a new particle system and at an energy… https://home.web.cern.ch/news/press-release/physics/lhc-experiments-cern-observe-quantum-entanglement-highest-energy-yet (Source of the original content)

More than 1,600 scientists, including two Nobel laureates, declare climate 'emergency' a myth

UPDATE:  The version of the story published on August 29 overbroadly characterized the exact language of the declaration itself regarding "greenhouse gasses." It has been corrected.

A coalition of 1,609 scientists from around the world have signed a declaration stating “there is no climate emergency” and that they “strongly oppose the harmful and unrealistic net-zero CO2 policy” being pushed across the globe. The declaration itself does not demonize carbon monoxide and does not discuss any harmful effect of other pollutants. The thrust of the declaration challenges the hysteria brought about by the narrative of imminent doom.

The declaration, put together by the Global Climate Intelligence Group (CLINTEL), was made public this month and urges that “Climate science should be less political, while climate policies should be more scientific.”

CLINTEL is an independent foundation that operates in the fields of climate change and climate policy. CLINTEL was founded in 2019 by emeritus professor of geophysics Guus Berkhout and science journalist Marcel Crok. 

“Scientists should openly address uncertainties and exaggerations in their predictions of global warming, while politicians should dispassionately count the real costs as well as the imagined benefits of their policy measures,” the declaration says.

Of the 1,609 scientists who have signed the declaration, two signatories are Nobel Prize laureates. The most recent to sign is Nobel Prize winner Dr. John F. Clauser, winner of the 2022 Nobel Prize in Physics. In an announcement from CLINTEL, Clauser is quoted as saying "Misguided climate science has metastasized into massive shock-journalistic pseudoscience. In turn, the pseudoscience has become a scapegoat for a wide variety of other unrelated ills. It has been promoted and extended by similarly misguided business marketing agents, politicians, journalists, government agencies, and environmentalists."

The 2022 Nobel Prize in Physics has been awarded to three scientists for their contributions to understanding quantum entanglement and advancing the field of quantum information.

Alain Aspect Institut d’Optique Graduate School – Université Paris- Saclay and École Polytechnique, Palaiseau, France

John F. Clauser J.F. Clauser & Assoc., Walnut Creek, CA, USA

Anton Zeilinger University of Vienna, Austria

The prize honors Alain Aspect of the University of Paris-Saclay and the École Polytechnique, John F. Clauser of J. F. Clauser & Associates, and Anton Zeilinger of the University of Vienna for developing experimental methods for probing entangled photons. The physicists’ work underpins quantum-based technologies such as quantum computing and quantum cryptography. The prize (approximately $900,000) will be shared equally among the laureates. Quantum entanglement refers to the way in which two particles are correlated, or tied to each other, even when they are separated by large distances. When one member of an entangled pair is affected—for example, by irradiating it with a laser—the result determines what happens to the other particle. The concept of quantum correlation remained largely a theoretical curiosity until the
