I didn't know that anything was different about me. OK, I have a formal diagnosis of ADHD but aside from that, at 50, I discovered that I am an Aphant and that I have a condition called Aphantasia, something I discovered by watching Season 1, Episode 7, of Space Force. Definition: the inability to form mental images of objects that are not present, "if counting sheep is an abstract concept, or you are unable to visualize the faces of loved ones, you could have aphantasia" "Aphantasia is a mental condition characterized by an inability to voluntarily visualize mental imagery. Many people with aphantasia also report an inability to recall sounds, smells, or sensations of touch. Some also report prosopagnosia, the inability to recognize faces."
