Yes, people blind from birth do dream, but their dreams are rich in sound, touch, smell, and taste, rather than visual images, as their brains generate experiences using the senses they know. While some might perceive abstract flashes of light or color, most report vivid sensory experiences without the detailed, memory-based visual scenes sighted people have. The key difference is that their dreams reflect their waking sensory world.
Although their visual dream content is reduced, other senses are enhanced in dreams of the blind. A dreaming blind person experiences more sensations of sound, touch, taste, and smell than sighted people do. Blind people are also more likely to have certain types of dreams than sighted people.
NARRATOR: Dreaming works in much the same way, as dreams merely reflect the world around us as we perceive it. Blind people therefore have non-pictorial dreams. The stories they play back in their heads are told by other means. KRÄMER: "We all have our own ways of imagining and grasping the world around us.
While people who have been blind since birth do indeed dream in visual images, they do it less often and less intensely than sighted people. Instead, they dream more often and more intensely in sounds, smells, and touch sensations.
The visual parts of the brain still ``remember'' and can replay past experiences. So the answer is: Blind people do dream, and their dreams are just as real and meaningful -- they're just shaped differently depending on their life experience.
The rarest type of dream is often considered to be the lucid dream, where you are aware you're dreaming and can sometimes control the dream's narrative, with only a small percentage of people experiencing them regularly, though many have had one spontaneously. Even rarer are dreams with specific, unusual content, like dreaming of doing math, or experiencing rare neurological conditions like Charcot-Wilbrand syndrome, where people lose the ability to visualize dreams.
In comparison, blind people's dreams include all senses except for the visual sense. Like Deaf people, they can also have a visual component in their dreams if they lost their vision after the age of five.
Yes, blind people close their eyes. Blinking and closing eyes are natural reflexes that protect the eye surface. However, some blind individuals might keep their eyes open more often, especially if they have light perception. The habit of keeping eyes open or closed can also depend on when vision loss occurred.
Actual answer: they fold the toilet paper to test if it sticks to itself. If it does, they're not done wiping.
On the other hand, most studies concur that the overall level of emotions in the dreams of blind individuals is similar or lower than that in sighted individuals [11], [12], [13], [14]. The thematic content of the dreams of blind individuals has received little attention.
Most blind people have some level of vision, but what they can see differs from person to person. Some may only see light. Others may see blurry shapes, figures, or colors. People with total blindness cannot see anything, but it is a misconception that they only see black or darkness.
During a 2018 interview with Rolling Stone magazine, Johnny Depp disclosed that he is blind in his left eye and short-sighted in his right eye! Whilst filming Pirates of The Caribbean, Johnny admits that he could barely see a few inches in front of his face… how disorientating.
Instead of seeing the latest image in real time, humans actually see earlier versions because our brain's refresh time is about 15 seconds. So this illusion demonstrates that visual smoothing over time can help stabilize perception.
Similarly to normally sighted individuals, the blind tend to have a superior memory for concrete imageable words than for abstract words (e.g., Cornoldi et al., 1979). Furthermore, “imagery” instructions facilitate word retrieval in both the sighted and the blind (e.g., Cornoldi et al., 1989, Jonides et al., 1975).
Sighted people don't rely solely on vision to determine when they're awake - they feel the bed and blanket, hear the outside world, and, if they're like me, have a deep-seated yearning for coffee. Blind people do the same.
REM sleep in blind individuals seems to be characterized by longer but less frequent episodes, with reduced or absent rapid eye movements [7,11]. Altered REM features, such as the alpha-like rhythm and sawtooth waves, have been reported [7,11], though these findings are not consistently replicated [12].
Total blindness is the complete lack of light perception and form perception, and is recorded as "NLP," an abbreviation for "no light perception." Few people today are totally without sight.
Tunisia, Morocco, Egypt, Jordan and other countries will use a small shower for rinsing off after you do your business. Most of these cultures believe that you can get your bum cleaner with water than you can with toilet paper which is why they chose that option.
Designed by Muna Daud, FlowSense is the world's first period blood detection device for blind and partially sighted women. It works by measuring the PH of vaginal fluids. Both period blood and regular discharge have different PH levels.
The koala is famous for sleeping around 20-22 hours a day, which is about 90% of the day, due to their low-energy diet of eucalyptus leaves that requires extensive digestion. Other extremely sleepy animals include the sloth (up to 20 hours) and the brown bat (around 20 hours), with some snakes like the ball python also sleeping up to 23 hours daily.
The 3-2-1 sleep rule is a simple wind-down routine: stop eating and drinking alcohol 3 hours before bed, stop working/mentally stimulating activities 2 hours before, and turn off screens (phones, TVs) 1 hour before sleep, helping you transition to rest by reducing stimulants and preparing your mind and body. It's often part of a larger 10-3-2-1-0 rule, which also adds no caffeine 10 hours prior and no hitting snooze (0) in the morning.
A blind eye may turn white due to several factors, with the most common being corneal scarring or cataracts. Corneal scarring occurs when the clear outer layer of the eye becomes damaged, often due to trauma, infection, or untreated eye conditions, leading to a cloudy or whitish appearance.
People who are born blind, or become blind early in life (before around five or seven years of age), do not experience visual imagery when they dream. People who became blind later typically do retain some visual imagery when they dream – but less so than in sighted individuals.
Just as a bilingual person might dream in different languages depending on the context of the dream, a deaf person might dream in sign language, especially if the dream involves communication with others. In these dreams, the brain engages with sign language as it would during waking hours.
Most hearing people experience their own voice in a silent way when thinking, which is also called “internal monologue”. Similarly, most Deaf people see pictures, ASL signs, or sometimes printed words. They see or feel their “inner signing”.
