What do blind people dream about? Can they "see" in their dreams? Take a look at scientific studies into the dreams of the blind, colorblind, and black-and-white dreamers.
In 1999, dream researchers at the University of Hartford analyzed 372 dreams of 15 blind people. They found that both the congenitally blind and those who went blind before five years old did not have any visual dreams at all.
People who go blind after seven years of age do report visual dreams in the same way we perceive them. It seems the longer you experience the world with sight, the longer you will go on dreaming visually. Someone who goes blind in their senior years can experience vivid dreams for many years after losing their sight.
Of the people who went blind between five and seven years the results were mixed; some went on to have visual dreams and some did not. However, regardless of the visual dream content, all groups reported rich and imaginative dreams, suggesting visual imagery is no measure of dream intensity on its own.
So, what do blind people dream about if there is no visual imagery involved? As a sighted person it's hard to imagine. But we can say that blind people's dreams are representative of their real lives, charged with sound, touch, smell and emotion.
Because they lack the sense of sight, their brains automatically compensate by putting more emphasis on the remaining sensory data. They can build up a highly detailed perception of the world (especially with advanced development of the senses such as echolocation) and these senses create a vivid dream world.
In one study of dreams, 60% of blind people reported dreaming about transport (compared to 28% of sighted people) which is understandably a big cause of anxiety for blind people because of the danger it presents.
Research has also shown that blind people who never dream visually show very little or no Rapid Eye Movement during the REM phase of sleep. They are still capable of having vivid sensory dreams, but they don't show any eye movements.
This highlights an interesting function of REM: our eyes dart all about the place because they're scanning a visual dream world. The fact that it's missing in the dreams of blind people suggest there is little or no other reason for REM.
What does this mean for colorblind people - do they dream in color?
As you might expect by now, your waking experience dictates your perception of dreams. So someone who has a red-green color vision defect since birth (affecting a surprising 8% of males with Northern European ancestry) will dream in the same colorblind mode.
If you were born with full color vision but later became colorblind, you may have full color dreams if you have sufficient intact long term memories of them.
Do you dream in color? For sighted people, this seems like a pretty odd question. If you see in full color during the day, then you dream in color at night, right?
Curiously, in 2008, researchers at the University of Dundee surveyed generations of people who grew up with black-and-white television (which emerged throughout the entire first half of the twentieth century).
Even though they saw in full color in everyday life, they still recalled dreaming in black and white. By the 1960s, when color TV became more widespread, people reported fewer black-and-white dreams and shifted back to full color.
Incidentally, if you can't recall any colors from last night's dream, this doesn't mean it was in black and white. It just means you don't recall that particular detail. Increasing your dream recall and practicing lucid dreaming will improve this.
Yes, I believe so. Blind people can have a highly attuned sense of self awareness, just like sighted people. In fact, they are more accustomed to using what we consider "back-up" senses as primary senses, meaning they can be more aware of their environment. This could enhance your ability to notice whether you're dreaming and become lucid. I wonder, what would those lucid dreams be like?
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.
To lucid dream is to examine an intensely heightened state of self awareness, with all the senses activated - a uniquely human experience. What's more, lucid dreaming offers profound benefits that touch all of us, no matter our culture, beliefs or life circumstances. Ultimately, I think all of these benefits put together could play a serious role in advancing the human race.
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...
