A bold new theory suggests that vivid dreams might actually be portals to existing alternate realities

Imagine waking up from a vivid dream where you were walking through an unfamiliar city, only to feel an unsettling sense of certainty that the place actually exists somewhere. For centuries, humanity has brushed off these nighttime wanderings as mere fragments of imagination. However, that might not be the case any longer. Scientist David Leong's latest research reveals some never-heard-before theories about dreams and their possibility of being linked to reality, which might force you to recall your dreams, as per Geek Spin's report on May 18, 2026.
Leong's study pushes a bold hypothesis that dreams might be a window into other realities. To put it simply, when a person is dreaming, the unconscious mind might be exploring a different layer of existence, where normal rules of space and time don't apply. Leong's hypothesis takes inspiration from Physics' 'Many Worlds' theory, which suggests that every decision creates a branching reality.
So, if we were to go by that theory in another reality at this very moment, you might be working the job you rejected, or perhaps you are in a different country. Nonetheless, Leong applies this very idea to consciousness, speculating that with the other senses relaxed while sleeping, the mind could have the freedom to bend the usual boundaries of time and space. He believes that dreams could be portals to alternate realities.

"At the macroscopic level, we assume objects have fixed properties like position or velocity. But quantum experiments challenge this assumption," he explains in his research. Nonetheless, this theory doesn't support all the dreams. According to his hypothesis, the ones that might actually exist in an alternate reality are recurring dreams, with consistent locations, characters, and ones that have structure and aren't completely random.
Even though there's still a lot of mystery around dreams, the majority of people are convinced that dreams are somehow connected to reality, especially recurring ones. According to a survey held by Purple, nearly 91% of Americans have had recurring dreams. Out of these, almost 60% of people report having their first recurring dream during their childhood or adolescent years. What's interesting is that nearly one-third of the adults feel these dreams are very realistic, with another 30% believing they are close to real.

Although there is no scientific evidence proving that humans can mentally communicate across long distances, some people point to discoveries in quantum physics as a reason the idea continues to fascinate researchers and the public alike. In fact, physicists Alain Aspect, John F. Clauser, and Anton Zeilinger won the 2022 Nobel Prize in Physics for their groundbreaking work on quantum entanglement. Their studies showed that paired particles can remain connected and influence each other even when separated by vast distances. This also highlighted that reality is far more interconnected and flexible than we believe, indicating that Leong's hypothesis might be true after all.
