Many have been astonished to discover the existence of aphantasia. Per Wikipedia:
Aphantasia is the suggested name for a condition where one does not possess a functioning mind’s eye and cannot voluntarily visualize imagery.
I believe I may have an even stranger condition, which I call Agnotphantasia. I am unsure of whether or not I am able to visualise imagery.
When I try to picture, for example, a goat, I am not sure whether I am in fact seeing a goat in my mind’s eye, or whether I am merely thinking of a goat, and some related concepts like horns. Sometimes I feel as if I can actually see something, sometimes I feel like I am merely pretending to myself that I can in fact see something.
I’m curious as to whether anyone else has had this experience.
