What does aphantasia do to your brain?
They have a condition called aphantasia. Aphantasia, which may affect as many as 1 in 50 people, happens when your brain’s visual cortex doesn’t work properly. Your visual cortex is the part of your brain that processes visual information from your eyes.
Can you be creative with aphantasia?
Cognitive tests and brain scans also indicate, however, that some people truly do lack the ability to form mental images. Aphantasia does not seem to impair creativity. Many aphantasics are successful in creative professions and have ways to compensate for their lack of a mind’s eye.
Can I picture things in my head?
Most people can readily conjure images inside their head – known as their mind’s eye. But this year scientists have described a condition, aphantasia, in which some people are unable to visualise mental images. Our memories are often tied up in images, think back to a wedding or first day at school.
Can blind people dream?
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. For example, blind people seem to experience more dreams about movement or travel7 and more nightmares.
How does aphantasia affect memory?
“People with aphantasia reported a reduced ability to remember the past, imagine the future, and even dream. This suggests that visual imagery might play a key role in memory processes,” explained Dawes. Some of those with aphantasia also reported decreased imagining with other senses.
Why can’t I imagine things anymore?

How are we able to see our imagination?
Cognitive scientists hypothesize that our ability to imagine, to come up with mental images and creative new ideas, is the result of something called a “mental workplace,” a neural network that likely coordinates activity across multiple regions of the brain.
