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...?

Books are a powerful way to increase our understanding and generate new perspectives. Good books are immersive and profound: they can change the way we live our lives. In teaching us new lessons, stripping away fallacies and inspiring independent thought, the following books on lucid dreaming are bestsellers for a reason - they are groundbreaking and thought-provoking reads to expand your awareness and develop your lucid dreaming skills.
Galantamine is best known for its ability to improve memory and provoke intense lucid dreams. Research by Dr Stephen LaBerge has found that taking galantamine intensifies your dreams on many levels, including cognition, lucidity, recall, control, bizarreness and visual vividness. If you want to boost your dream life, and maybe prompt some lucid dreams, it's worth taking the occasional galantamine supplement.
Why write a book about how to "hack" sleep? Well, I've suffered from sleep issues throughout my entire adult life. Sleep was such a tough thing to figure out. It didn't respond to willpower. I could beg and cry and kick and scream to myself to fall asleep, but my body would not listen. Finally, I realized that enough was enough and that I was going to fix this very important area of my life for good, or at least do my best to try. I spent nearly one year constructing a system to improve the quality of my sleep.
Humans are unique in our endless capacity for imagination. According to Steven Mithen, an anthropologist at the University of Reading in the UK, we needed to evolve seven critical mental skills before we could have imagination as we know it. Each of these abilities serve a distinct purpose in their own right, while imagination is the culmination of them all.
This dream starts out pretty violent but then suddenly goes all profound on me. I'm having a nightmare in which a thin, gray-faced man is trying to kill me. I become lucid and battle him with ease, firing shots of lighting out of my hands and hitting him in the chest. He falls to his knees and I lock him in a gated prison using only my mind. But then my lucid dream evolves into a lucid nightmare. Another villain, who looks like Krang (or Krang's body at least) from that delightful cartoon about giant mutant turtles, frees the gray man using his telepathic powers. I am no match for him.
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?
