CrowdScience listener Eileen cannot see images in her head of her memories. She only discovered by chance that most other people can do this. She wants to know why she can\\u2019t see them and if it is something she can learn to do.
Anand Jagatia finds out what mental images are for and whether scientists know why some people can\\u2019t create them.
Three per cent of the world\\u2019s population cannot see mental images like Eileen. And it is only recently been given a name \\u2013 aphantasia.
Anand discovers why mental images are useful, why they are sometimes traumatic and how people who are blind or visually impaired can also create images of the world around them.
