Dr Keith Hearne is a British psychologist and the first person to create scientific proof of lucid dreaming in the laboratory via his ocular-signalling technique, in 1975.
Dr Hearne went on to perform many more experiments in the realm of dreams and premonitions. In this exclusive interview, Dr Hearne talks about the moment he received the first conscious signals from a lucidly dreaming individual, as well as the ensuing physiological and psychological discoveries made on lucid dreaming for his PhD.
No one before had ever witnessed what I saw in the sleep laboratory at Hull University, England at about 8am on the morning of 12th April 1975.
The previous night I had instructed the male subject who reported having fairly frequent 'lucid' dreams (in which the dreamer becomes fully conscious and has full critical cognitive faculties whilst still in the dream) to make seven or eight left-right eye-movements on becoming lucid.
After all, REM means Rapid Eye Movement sleep, so surely the ocular muscles could be operated deliberately when lucid. I had devised the signalling method in an attempt to circumvent the profound bodily paralysis of REM (dreaming) sleep - which inhibits any physical signalling.
The subject was 'wired up' to a sensitive multi-channel chart recorder. With great anticipation, I had been watching each REM-period during the night. Just before 8am the subject had been in indubitable REM sleep for about half an hour.
There was a long REM burst, nothing unusual, when, suddenly, out of the randomness, the requested, deliberate, sequence of large zig-zag movements appeared in the two channels monitoring eye-movements:
A sequence of left-right ocular signals, recorded at Liverpool University using a Grass polygraph. Note the pre-lucid REM burst preceding the signals, an effect discovered by Dr Hearne.
EEG - Electro-encephalograph (brainwaves trace) EOG - Electro-oculograph (eye-movement trace) EMG - Electro-myograph (muscle activity trace)
On waking, the subject described how he suddenly realised he was dreaming, and consciously made the signals before continuing the lucid dream experience. They were the first ever signals communicated from within a lucid dream.
It was like getting SETI signals from another solar system. I was ecstatic, but had to keep quiet not to awaken the subject!
It was an amazing, mind-boggling, situation. I was looking at a communication from a person in another room who was asleep, 'unconscious', dreaming, yet in his own vivid world in which he was perfectly conscious and interacting with others. It was his reality - I was in my reality. A channel of communication had been established between those two realities.
The original chart-record, and my dream machine invention, are now on permanent display in the London Science Museum. The whole PhD thesis and my book The Dream Machine2 may be downloaded for free at my website KeithHearne.com.

The technique opened up a doorway into a whole new area in dream research - the dreamer was able to send out real-time information, say on experiments, conducted in the strange environment of the inner-space universe. (On another 12th April, in 1961, Yuri Gagarin first went into the outer-space universe.)
A few months later I was given my own sleep-laboratory at Liverpool University, and over three years discovered the basic physiological and psychological phenomena of lucid dreaming, for my PhD1.
Among the discoveries were:
I sent news of my signalling discovery to two well-respected sleep researchers: Professor Allan Rechtschaffen at Chicago University, and Professor William Dement at Stanford University. Rechtschaffen sent a most encouraging reply. Several years later, research conducted in North America confirmed my findings.
I am very honoured that April 12th is now being recognised as Lucid Dreaming Day to mark this breakthrough research.
I'm fascinated by premonitions. Alongside my main lucid dream work, I had performed many experiments (some using very advanced technology) into parapsychology, in the very artificial situation of the laboratory - with mixed results - but then one day I had a 'real life' experience.
I was about to make a familiar, routine, ferry journey across the broad Humber estuary when I 'knew' with complete certainty that something untoward was going to happen on that vessel. I'd never had such a feeling before. I stopped and thought, but decided to go aboard. On the journey it got dark, and later there was a cry of 'Man overboard!' Someone had actually fallen into the water. After a long time of searching, the passenger was dragged on board. I saw resuscitation being performed.
The event spurred me to investigate real-life premonitions. Later I wrote a book on my fairly extensive research called Visions of the Future4.
An analysis of cases identified a sub-group of premonitions that seem to be very accurate, which I termed 'Media announcement type' - say TV, radio, newspaper, items that are seen/heard before the unexpected event. One such case concerned the Flixborough chemical plant disaster in the UK.
These anomalies must be considered in our attempts to make sense of this amazing world in which we find ourselves. Simple explanations are not enough.
I think ordinary dreams can indeed be 'metaphors in motion'5,6,7are a way by which the unconscious can provide useful information to the dreamer.
I would recommend readers to look at The Dream Oracle8 book by David Melbourne and myself. David came up with the extraordinary technique, which is based on the letters of the alphabet, and provides a completely new method - greatly facilitating that communication.
I enjoy writing music - and had a fantastic time composing the music for a full-length ballet called Princess of The People in conjunction with Dame Gillian Lynne (who choreographed Andrew Lloyd Webber's Phantom of The Opera andCats). Some pieces were recorded for a CD by the Moscow Symphony Orchestra.
Other compositions include a full Requiem, a Musical, a Guitar Concerto, a Holocaust Memorial piece, an Anthem for Armenia, and several Songs (including religious pieces separate from the Requiem - Ave Maria, Pie Jesu, Nunc Dimittis, Magnificat, Our Father), and a 'Cello concerto. Currently I'm working on an exciting Opera.
Some of my music originates in the wonderfully creative source of the dream world. On waking, I dash to the synthesizer to record the fragment!
I know what triggered my interest in visual imagery, then dreams. As a child of about six, my teacher said to me: "You know when you daydream, Keith, and see pictures...". I was puzzled by what she was saying, but I realised later that I have no visual imagery (in wakefulness) whatsoever. Other children though, were saying "Yes Miss". I realised at that early age that there are major individual differences in people.
The thought stuck in my mind. Later, when an older sister was at College, she brought home books by Freud, Jung, etc. I read them avidly, so that also cemented my interest in dreams.
As an undergraduate at Reading University in England, I developed a 'tracing' technique enabling subjects, in hypnosis, to externalise their internal imagery9. I termed the method 'hypno-oneirography'.
The subject sits in front of a large drawing board, in hypnosis, and is instructed to have a vivid hypnotic dream (or even to explore a 'past life'). The dream imagery is stopped on command, then the subject opens their eyes, 'projects' the freeze-framed image onto the board and traces the image. Colours are described, and later painted-in. Sequential stop-starts can reveal scenes from a whole imagery-experience.
A 'scene-change effect' was immediately discovered. It seems that the 'pixels' of the 'before' picture simply get re-arranged into a new scene, by a 'law of least-effort'. These effects occur in nocturnal dreams too. I'd like to see my effect in a Hollywood film!
The Scene Change Effect Using Hypno-Oneirography
When anyone is a pioneer in a new field, a few over-enthusiastic individuals will try to 'jump on the band-wagon', and make claims of association and even priority. So, some people (mostly in America) have completely the wrong idea about the beginning of sleep-lab research into lucid dreaming, and my pioneering role. Lazy journalists have unintentionally perpetuated that misinformation.
Things are changing now, I'm pleased to say. The internet has been good for this - all the information is there, for all to see. Those new, modern writers who demand accuracy in memorialising the history of science (such as Daniel Love) are steadily putting the record straight.
I'm well into writing a major book now, which introduces new concepts. It will upset some people. Also, I'm composing a dramatic opera based on a real person from history. I'm also contributing to the English translation of Hervey St Denys' landmark book on lucid dreaming, a project called Translating Dreams, now fundraising on KickStarter. I have a few inventions I'd like to work on, too - but I have to ration my time!

If we're completely honest, lucid dreaming isn't really known for being the most social of interests. In fact, often it's a lone pursuit - just you, your dream journal and the landscape of your mind. But this technique called PAL (or Partner Assisted Lucidity) breaks down that wall and turns lucid dream exploration into a social event.
Members of our lucid dream forum have been asking how to create dream characters in lucid dreams. The most common problem is having characters who look nothing like they should. Or they seem disinterested in your company. Or they fail to show up on command altogether. So, how to combat this? It's a matter of finding creative solutions that bypass logical expectations.
To lucid dream, I recommend being able to remember at least one vivid dream per night. That will boost your self awareness in dreams (making lucidity more likely) and also means you can actually remember your lucid dreams. Which is nice. Here are four detailed tips on how to remember your dreams more frequently. And if you don't think you dream at all - trust me, you almost certainly do. It takes an extraordinarily rare sleep disorder to deprive someone of dream sleep.
It is estimated that these wise and wily Indians have been using mugwort in their healing and ritual practices for 13,000 years, where it is known as the ‘dream sage’. They use the herb to promote good dreams, which they consider an essential aspect of normal human functioning! But that’s not all...
Silene Capensis has been used for millennia by the Xhosa shaman of the river valleys in the eastern cape of South Africa, where it is known as Undela Ziimhlophe or 'white paths'. It's fragrant white flowers open only at night, when they emit a fragrant and almost hypnotising aroma. Also known as African Dream Herb or Ubulawu, Silene Capensis induces spectacularly vivid dreams - yet has never entered the mainstream and remains a fringe taste within western culture.
Experts agree that everyone is capable of having lucid dreams. Dreaming itself is a normal function of the mind. We all dream every night, even if we don't remember. And we all achieve conscious awareness while awake every single day. So what does it mean to combine these states? Why, the amazing ability to have conscious - or lucid - dreams. Sounds simple, doesn't it? So why do I keep hearing from people who say they can't achieve their first lucid dream?
