Why can't I fully picture people's faces in my imagination?
Aphantasia is a condition in which a person is unable to visualise mental images [1, 3]. It is thought that as many as one in fifty people might have this condition [3]. Some report that its lack of ability to visualize things makes them feel "alone" or "isolated" [3].
Aphantasia is the inability to voluntarily create mental images in one's mind. The person with aphantasia is often aware that he or she has a blank mind's eye and may feel "alone" or "isolated" as a result. [1] Aphantasia may affect as many as one in fifty people. One study of 41 people with aphantasia found that three of them had difficulty visualizing faces. [2, 3]
