Some people find it impossible to imagine a friend's face or their own apartment - a phenomenon named aphantasia.
Scientists have described a condition, aphantasia, in which some people are unable to visualise mental images.
I have a condition called aphantasia where I can't visualise things. When I try to picture my daughter when she's not there, I see nothing.
Aphantasia is a relatively rare condition that affects 2% of the population, and both genders equally, says Professor Zelman.
A small proportion of healthy individuals, perhaps two or three in a hundred, lack visual imagination completely, a phenomenon we have termed aphantasia.
