How are blind people born with dreams?

If the dream of a normal person will be images that more or less they have "seen" in life, for the blinds who are born naturally the world around them is only a black color, they what will you dream This is probably a question of not only my own but many other friends. It turns out that the voice, the scent of the body, the feeling of grasping, the feeling of someone else's hand, . is what blind people will "see" in their dreams. For more details, please see below.

First, please approach the problem with a little challenge: take a minute to recount your dream last night. Certainly you will slowly remember the story or thing that you encountered in your dream, whether vague or truly clear. The reason you do it is like many other people: you know because you've seen them. Dreams are mostly visual images, strongly influenced by things we see while we are awake. So in fact. People who grow up with a black and white TV will tend to see dreams in gray.

Dreams are mostly visual images, strongly influenced by things that we see while still awake.

However, if you do not have any images to build, your brain must use other materials to build up the world in dreams, creating a period of incomplete sleep. In a sense, it helps people continue to receive the coming days of life. On the University of Illinois science website, one uses the notion that: "Our dreams are based on memories. So a person who has never experienced" seeing "will not dream with sight. Just like the average person cannot have ultrasound dream dreams because the human eye cannot recognize it. "

Sensory characteristics in dreams like blind people will be very rare.

Tommy Edison, owner of the Youtube Channel Blind Film Critic, said in a dream, "people around me appear to me in ways I know about them." Edison is a natural blind man and he says he can interact with others in dreams through sound, taste and sometimes touch. He said: "If I ever met you in a dream, what I know will be your voice and maybe the perfume you wear. If someone takes me in the past, I can know. they dream in their hands. "

However, for those who are not blind, research has shown that the sensory characteristics in dreams like blind people will be very rare. In a study published in 2014 in Sleep Medicine magazine, researchers asked 50 volunteers to follow their dreams for 4 weeks. Eleven of them were born blind, 14 were blind at some time during adulthood, and 25 others had normal vision as a control group. The results showed that the researchers did not detect any major differences between the three groups in terms of content or emotion in the dream. However, they discovered some big differences about how they experience the dream world.

Blind people can smell the scent of dreams twice as high as those with normal vision.

Just like in normal daylight, the dreams of both groups of blind people are mainly based on their remaining four senses: 86% of the blind say that they are less likely to hear the sounds in their dreams , while the average group is 64%; 70% of the blind said there was a feeling of touching in the dream, while only 45% of ordinary people had this; Lastly, the rate of blind people who smell the fragrance in dreams is twice as high as those with normal vision, with a ratio of 30 to 15%; Lastly, the blind can dream of tasting the flavor at the rate of 18%, while ordinary people only have 7%.

However, if you focus more closely on the group of people who have been seen in your life but then become blind, it is different from the ordinary smaller ones. In particular, those who have had memories seen in the past can still build their dreams , filling in the image gaps with their own imagination. A person who once saw blindness said: "For the people I have met after blindness, their faces become blurry or will show an image that I imagined. However, people like my mom will forever have faces at the age of 30 ".

Nightmare is a form of interpretation for threats in real life.

Normally, visual memories will become fuzzy over time, the images will become more blurry and appear less, eventually people who are blind at some time in their lives will come to There are dreams like those born blind.

Congenital blind people in the study in 2014 also tend to have more nightmares. This finding further reinforces the argument that nightmares are a form of interpretation for real life threats. Accordingly, children are more vulnerable than adults, so they often have scary dreams. Similarly, it is possible that people with disabilities, losing their sight, thus losing their normal sight, the brain tends to create exercises to help them be more ready for dangerous situations.

And for Edison, the most terrible nightmares as well as happy dreams are mostly happening by hearing. He said: "I worked in a radio station for a long time so I mainly had audio dreams. When the tape was over, I had no sound and everything else was only spaces. dead, completely quiet ".
