While ancient dream theories were mostly unscientific in their approach, they reveal our long-held desire to explore the hidden depths of the dreaming mind.
Today, dream research extends in many directions, and every year scientists around the world make new discoveries about the nature of the dreaming brain with biological, psychological and technological implications.
So how did we get here?
There is evidence dating back some 5,000 years, when the Ancient Egyptians painted pictures of the sleeping body (Ka) and the soul (Ba) hovering outside it, in the style of an out-of-body experience (which modern dream research has linked closely to lucid dreaming).
This tells us that people who lived thousands of years ago not only experienced OBEs and lucid dreams - but it was a common enough occurrence to have become a part of their culture, just like it is today.
We also know that, at least 1,000 years ago (and likely much longer) Tibetan Buddhist monks practiced a form of lucid dreaming known as Dream Yoga.
The monks used their dream world in an extraordinarily profound way - to study the depths of human consciousness and use it as a path to enlightenment. The art form can be learned to this day via works such as The Tibetan Yogas of Dream and Sleep.
In the 1600s, the French philosopher Rene Descartes propagated The Dream Argument. It states that our dreams provide evidence that our reality isn't actually "real" at all... The argument is based on two observations:
In the East, the dream argument is well known as Zhuangzhou Meng Die (translated as Zhuangzi Dreamed He Was a Butterfly). After he woke up, Zhuangzi philosophized over whether he was a man who had dreamed he was a butterfly - or a butterfly who was dreaming that he was a man...
Indeed, this idea is woven throughout Eastern philosophy, and some schools of thought in Buddhism state that reality is not real in a very literal sense. As Chogyal Mankhai Norbu suggested: all of our waking sights, sounds, smells, tastes and tactile sensations are merely part of a much larger dream.
This line of thinking has infiltrated Western culture through movies like The Matrix. But this goes way beyond fiction. The Swedish philosopher, Nick Bostrom of Oxford University, has built a scientific theory called The Simulation Argument. The bold conclusion of his probability equations is that we are almost certainly living inside a computer simulation: we are the digital dreams of future human beings.
Sigmund Freud, the father of psychoanalysis, is famous for his psychoanalytical theories of dreaming. He believed dreams are an outlet for repressed desires, that would otherwise wake us from our slumber. In Freud's view then, dreams exist to preserve our sleep.
In the 1970s, Hobson and McCarley did an experiment that suggested the origins of dreams are merely random electrical impulses firing from the brain stem. The researchers managed to track dreamer's brainwave activity using an EEG machine, and create a predictable mathematical model for this physiological process. According to their findings, dreaming is a bodily process - not a mental one.
The only gap in this theory (and it's a big one) is that dreams do actually make sense; so they can't be fully explained by these random electrical firings.
So Hobson extended the theory with a psychological basis for dreaming. And it flew in the face of Freud's theories of sexual repression. After the brain's cortex receives the random energy signals, the dreaming mind tries to make sense of them based on unconscious reasoning - i.e. lessons we have taught it from our experience of waking life. These "rules" aren't necessarily accurate, they are simply our perceptions of the world.
For example, you may believe that all men are murderous. This is great fodder for a dream about being chased by a male attacker. Yet the dream itself simply means you are running away from a source of fear. It's a common enough dream, made personal by our own personal fears, and not nearly as cryptic as Freud would have us believe. In fact, Hobson claims, our dreams reveal far more than they hide and we should shrug off "the mystique of fortune cookie dream interpretation".
In our timeline of dream studies, we might ask who discovered lucid dreaming?
There is no single person responsible for "discovering" lucid dreaming. It is an innate skill we have evolved as human beings, such as being able to communicate through verbal language, or even think with an internal monologue.
It's a high-functioning ability, and we can currently only attribute lucid dreaming to humans. That's because to lucid dream, we need two things:
Lucid dreaming is not as prevalent in the human population as the ability to communicate verbally, or think in words. But it has nonetheless penetrated our cultures for millennia and shone a brighter light on the mysterious dreaming mind.
In the Western world, the term "reve lucide" (lucid dream) was first identified by Marquis d'Hervey de Saint-Denys in 1867 in his book, Les Rêves et les Moyens de les Diriger; Observations Pratiques - which translates as Dreams and the Ways to Direct Them: Practical Observations.
The Dutch psychiatrist, Frederik van Eeden, experienced lucid dreams, and wrote in his 1913 book, A Study of Dreams:
"In these lucid dreams the reintegration of the psychic functions is so complete that the sleeper remembers day-life and his own condition, reaches a state of perfect awareness, and is able to direct his attention, and to attempt different acts of free volition... We are here, however, on the borders of a realm of mystery where we have to advance very carefully. To deny may be just as dangerous and misleading as to accept."
Half a century later, the British philosophical skeptic Celia Green recognized that lucid dreaming is a separate state of consciousness - distinct from both regular dreams and waking awareness.
Green also published many accounts of lucid dreams, out of body experiences and apparitional experiences, and postulated that they all have something in common. Namely, that the subject's field of perception is entirely replaced by a hallucinatory one. Evidence for this hypothesis is presented in her book, Lucid Dreaming: The Paradox of Consciousness During Sleep.
As a result of this dream science and more, lucid dreaming has advanced our understanding of the dreaming mind, revealing an extraordinary capacity for conscious thought while asleep that is still not fully understood to this day.
For those who believe dream science is old hat - think again. Here is a smattering of just some of the recent discoveries in the field of dream research:
A lot has happened in the last 5 months. But how did we go from business as usual to changing the face of the entire lucid dreaming supplements industry? It’s a story that I think will interest you – and you might even learn a thing or two in the process. When I was first taken on-board as Chief Lucidity Officer in 2016, one of the first things I was tasked with was taking a good look at our operations and giving things a bit of an overhaul.
Gather round. I’ve a story to tell. It’s a story of tragedy, re-birth and fresh beginnings... But fear not, it has a happy ending! Our forum had some pretty impressive stats at its peak: 60,171 posts, 134 people online at once and over 10,000 registered users.
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.
Years ago, before I had my first lucid dream, I had a very specific idea about what a lucid dream would feel like. I thought it would be intense and magical and a little bit spooky. This turned out to be a pretty accurate representation. Becoming aware in the dreamstate is like entering another world. One where physical laws can be manipulated (there is no spoon, Neo) and your fantasies can come true in an instant. There's definitely something magical about that - and it's as if the lucid dream world is a living, breathing organism that can react to your very thoughts.
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?
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...
