What do blind people dream about? This article highlights the latest studies into the dreams of blind people, colorblind people, 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.
That's because our dreams are made up of real world experiences and our innermost thoughts, anxieties and desires. So for someone who has never perceived images or light (or can't remember any) their dreams simply can't manifest visually.
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 pretty 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 sleep: the only reason our eyes are darting all about the place is because they are scanning a visual dream world. The dreams of blind people suggest there is no other reason for it.
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. This aspect of visual memory is interesting; for instance people who became blind later in life report how familiar faces become blurry with time - and they never age.
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 - surely?
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 - and 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 own environment. This could enhance your ability to notice whether you're dreaming and become lucid. What would those lucid dreams be like...?

Did you know that learning how to visualize with maximum definition can give you more lucid dreams? That's because visualization is key to a range of popular lucid dreaming techniques. Daydreaming visually can even program your regular dream content. For some people, visualization comes naturally, so the exercises here may seem obvious. But for others, engaging the visual imagination is tough. So I'd like to share some of my own visualization styles which might help.
The evolutionary biologist Robin Dunbar once said: "What sets us apart is a life in the mind, the ability to imagine." What, then, is it like to live without any trace of visual imagination? With no mind's eye to "see" your daydreams and memories? No way to recall the tastes of your favorite foods, summon mental images of loved ones, or visualize landscapes and characters described in novels? This is the arguably disturbing reality for 1 in 50 people who are coming to terms with the fact that they suffer from a newly named condition called aphantasia.
On the surface, this seems like an odd question to ask. Everybody feels like they have their own free will - whether it's a big decision like choosing their life partner, or a minor call like whether to keep reading this article. But when you break down the neurological process of conscious decision making, there is a distinct lack of evidence for free will. Scientific theories on cause and effect - and philosophical theories about the self - frequently rule out any need for a conscious decision maker at all.
If you saw the Christmas edition of Charlie Brooker's awesome Black Mirror [spoiler alert] you would have watched Jon Hamm mentally and emotionally torture an innocent woman living inside an egg. Ok, back up a bit. She wasn't really a woman. She just thought she was. One week earlier, Hamm's technical team implanted a 'cookie' into a real woman's eyeball. The cookie was an artifically intelligent computer chip. And over the next seven days it learned the personal preferences, thoughts and emotions of its female host. It even took on her life's memories.
Dream herbs are used to induce lucid dreaming, which, most accurately is described as an awareness that you are dreaming to the point that you can control dreams. But, on a more basic level, dream herbs also seem to be linked to increased dream recall or simply an awareness that you are dreaming even if you cannot control the dream. Today I'm going to summarize the best dream herbs for lucidity - as well as where to buy the seeds, how to grow and cultivate them, and what effects that have on your dreams.
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?
