How Keith Hearne, Stephen LaBerge and Paul Tholey turned dreams into data
Lucid dreaming—the phenomenon of becoming consciously aware that you’re dreaming while dreaming—has long fascinated philosophers, mystics, and scientists alike. But for centuries, it remained speculative.

That is, until the late 20th century, when lucid dreaming finally crossed the threshold into scientific legitimacy.
So who actually proved lucid dreaming?
Who was first?
And how did we get here?
Let’s walk through the full, factual timeline—and settle the debate once and for all.
Pre-1970s: Foundations of a Dream Revolution
Before any lab experiments, the idea of lucid dreaming was already known. Ancient texts referenced conscious dreams, and by the 19th century, Western thinkers had begun documenting them seriously.
1867 – Marquis d’Hervey de Saint-Denys publishes Les Rêves et les Moyens de les Diriger, describing techniques to influence and become aware in dreams.
1913 – Frederik van Eeden coins the term "lucid dream" in English, describing over 350 dreams with self-awareness.
1968 – Celia Green publishes Lucid Dreams, one of the first scientific discussions linking lucid dreams with REM sleep.
1974 – Patricia Garfield’s Creative Dreaming introduces lucid dreaming to a popular audience and explores dream control.
But still, lucid dreaming had not yet been objectively proven.

1970s–1980s: Paul Tholey and the Psychology of Lucidity
Before others were in the lab eager to prove lucid dreaming could be measured, a quiet revolution was happening in Germany—one that would shape how we actually experience lucidity.
Location: University of Frankfurt, West Germany
Researcher: Dr. Paul Tholey
Subjects: Over 200 students, plus psychotherapists, case studies, and thousands of dream reports
Tholey, a Gestalt psychologist, wasn’t chasing eye signals or lab machines. Instead, he was on a mission to map the inner logic of dreams. Through a mix of rigorous experimentation and philosophical insight, he developed one of the most practical and enduring systems for lucid dream induction.
His most famous contribution, the Reflection Technique, taught dreamers to develop a questioning mindset by regularly asking, “Am I dreaming?” during waking life. When practiced consistently, this habit often carried over into dreams—triggering lucidity organically, without external gadgets.

But Tholey went deeper. He explored how dreamers could interact with dream figures, manipulate dream content, and use lucidity as a therapeutic tool. He even documented cases where dream characters displayed independent thought, memory, and motivation—long before AI made that idea trendy.
In 1983, he published a landmark paper, Techniques for Inducing and Manipulating Lucid Dreams, outlining a complete framework for entering, navigating, and learning from lucid dreams—much of which is still relevant and used today.
Key Facts:
Tholey’s methods were grounded in Gestalt psychology, not fringe speculation.
He tested his techniques on over 200 subjects, plus thousands of dream reports.
His Reflection Technique directly inspired many of LaBerge’s later ideas.
He emphasized lucidity not just as a skill, but as a tool for philosophical insight and emotional growth.
His work was methodical, rational, and deeply human—yet remains underappreciated outside of Europe.
Tholey may not have sent eye signals from a lab, but in many ways, he was the first serious explorer of the lucid dream landscape.
Where others proved lucidity, Tholey mapped its terrain.
April 12, 1975: The First Scientific Signal – Keith Hearne
The turning point came quietly.
Location: University of Hull, England
Researcher: Dr. Keith Hearne
Subject: Alan Worsley, volunteer lucid dreamer
On April 12th, 1975, at 8:07 AM, Worsley became lucid inside a dream and performed a pre-arranged left-right eye movement while being monitored by an electrooculograph (EOG).
The signal appeared clearly on Hearne’s recording equipment—zigzagging across the page in deliberate motion.

This was the first time in human history that a message was consciously sent from within a dream and recorded by scientific instruments.
Hearne documented the work in his PhD thesis (submitted in May 1978) at Liverpool University and later published it in a peer-reviewed parapsychology journal, the Journal of the Society for Psychical Research. He also developed an early REM-detection device, dubbed the "Hearne Dream Machine", which would later inspire future technologies like the NovaDreamer.
Key Facts:
Hearne’s 1975 experiment was the first scientific demonstration of lucid dreaming.
It used EOG only—not full polysomnography.
His research was largely ignored by mainstream science due to the parapsychological publication route.
He maintains he sent his results to multiple institutions—including Stanford.
1978–1981: Stephen LaBerge and the Rise of Mainstream Acceptance
Unbeknownst to Hearne, another lucid dreamer-scientist was pursuing a parallel path.
Location: Stanford University, California
Researcher: Dr. Stephen LaBerge
Subject: Himself
On January 13, 1978—also a Friday the 13th—LaBerge successfully performed eye signaling from within a lucid dream, confirmed by a combination of EEG (brain waves), EOG (eye movements), and EMG (muscle tone). This use of full polysomnography ruled out the possibility that he was awake or in any state other than REM.

He went on to repeat the experiment across multiple subjects, refining the protocols and submitting his data to peer-reviewed journals.
December 1980 – Publishes “Lucid Dreaming as a Learnable Skill: A Case Study” in Perceptual and Motor Skills.
1981 – Publishes follow-up paper showing multiple successful lab-verified signals during REM sleep from trained lucid dreamers.
This work marked the scientific mainstreaming of lucid dreaming. While Hearne had done it first, LaBerge’s rigor, replication, and persistence brought widespread academic recognition to the phenomenon.
Key Facts:
LaBerge was unaware of Hearne’s prior work at the time of his research.
His method was more robust, using EEG, EMG, and EOG to fully confirm REM sleep.
His research was repeated, published, and peer-reviewed in respected journals. Despite considerable skepticism and early rejections from major publications, he persisted—eventually securing mainstream scientific recognition for lucid dreaming.
He later founded the Lucidity Institute, trained thousands, and developed induction devices like the NovaDreamer.
Parallel Discovery: A Common Scientific Theme
Some debates argue over who gets the credit for "proving lucid dreaming"—Hearne or LaBerge. But scientific history is full of parallel discoveries:
Newton and Leibniz with calculus
Darwin and Wallace with evolution
Edison and Swan with the light bulb
Ideas often emerge independently when culture, technology, and curiosity converge. The 1970s were exactly that kind of moment for lucid dreaming. Sleep labs were proliferating. REM research was booming. Dream control was entering public consciousness.
While Hearne later speculated that LaBerge may have known of his earlier experiment—claiming to have sent summaries to Stanford in 1975—there’s no clear evidence LaBerge ever saw these materials. He has consistently maintained that his research was conducted independently, and given that Hearne’s findings were published in a niche parapsychology journal with limited academic visibility, this remains the most plausible scenario.
Hearne’s work was ground-breaking, but its reach was constrained by the path he chose for publication. LaBerge, by contrast, pushed for recognition in mainstream scientific circles—giving lucid dreaming the broader legitimacy it needed to grow.
In the end, Hearne and LaBerge were simply the right minds at the right time.
The Hearne Dream Machine: Ahead of Its Time
Following his 1975 success, Hearne developed a REM-sleep detection device that used respiratory changes to cue a dreaming subject. When REM was detected, it delivered mild electrical skin stimulation intended to influence the dream or cue the sleeper to become lucid.
While it had limited practical success (participants rarely became lucid), it was the first attempt at external dream cueing—an idea that LaBerge would later expand on with the light-flashing NovaDreamer.

Scientific Legitimacy Today
Thanks to the combined efforts of LaBerge’s scientific rigor, Hearne’s pioneering experiments, and Tholey’s psychological insights, lucid dreaming is now
recognized by:
Mainstream sleep science
Neuroscience publications
Psychology curricula
Global academic institutions
Modern studies use real-time communication in dreams, brain imaging, and targeted memory reactivation to explore lucidity. Lucid dreaming is also used therapeutically for nightmares, PTSD, and emotional processing—an approach anticipated by Tholey’s early work in dream psychology.
Tholey's emphasis on the therapeutic and philosophical value of lucid dreams has helped frame them not just as a scientific curiosity, but as a legitimate tool for introspection, cognitive development, and mental well-being.
Thanks to these multidisciplinary foundations, lucid dreaming is now embraced worldwide as both a subject of scientific interest and a practice of personal exploration.
So, Who Proved Lucid Dreaming, LaBerge, Tholey or Hearne?
Well, the answer to that is... Yes:

So… Who Really Proved Lucid Dreaming?
If you're looking for a single name to credit, you're missing the bigger picture.
Yes — Keith Hearne was the first to scientifically capture a signal from within a lucid dream.
Yes — Stephen LaBerge was the first to bring lucid dreaming into the scientific mainstream through rigorous, repeatable research.
And yes — Paul Tholey was the first to build a comprehensive psychological framework for lucidity, offering practical tools and philosophical depth that still shape the field today.
But none could have done it alone.
Their discoveries were only possible thanks to a chain of scientific advancements stretching back decades:
Hans Berger, who developed EEG, the technology that let us monitor brainwaves.
Aserinsky and Kleitman, who discovered REM sleep in 1953 and opened the door to dream science.
William Dement, who built the foundations of modern sleep research and mentored LaBerge at Stanford.
Celia Green, who connected lucid dreaming with REM sleep in a pivotal 1968 publication.
Add to this the thinkers who shaped the philosophical and psychological landscape—Saint-Denys, van Eeden, Freud, and others—and it becomes clear:
Lucid dreaming wasn't "proven" by one person. It was revealed through a collaboration of minds across time.
It was Hearne’s spark, LaBerge’s persistence, Tholey's passion, and a century’s worth of tools, theories, and courage that turned dreams into data.
And thanks to them, we no longer have to ask whether lucid dreaming is real.
We can ask what we might do with it next.
Conclusion: Dreamers of the Lab
The scientific validation of lucid dreaming wasn’t one moment—it was a layered journey. A quiet British researcher caught the first signal. A tenacious American lucid dreamer made the world believe it. And both helped launch a movement that continues today.
So the next time you become aware inside a dream, take a moment to remember: that ability was once debated, doubted, and finally—proven.
Dreams aren’t just stories. They’re a field of science.
And it all started with a few eye movements… and a lot of sleepless curiosity.
