Aphantasics report no conscious mental imagery. Some aphantasics, while they don't have any visual imagery when deliberately trying to conjure up images, do have involuntary flashbacks of images. Differences in Dreaming Experiences Among AphantasicsThe most important — and puzzling — difference among aphantasics is that some dream in images, whereas others don't. How can aphantasics, who can't conjure up images when they are awake, have rich imagery when dreaming? More specifically, while some aphantasics have problems conjuring up mental imagery at will — for example, counting to three and visualizing an apple — their involuntary mental imagery is intact.
