Aphantasia - Condition where one does not possess a functioning mind's eye and cannot voluntarily visualize imagery. The lack of an inner monologue has been linked to a condition called aphantasia — sometimes called "blindness of the mind's eye." People who experience aphantasia don't experience visualizations in their mind; they can't mentally picture their bedroom or their mother's face.
This is shocking to me, I cannot fathom how I could survive without my inner voice, it's what keeps me sane.
This condition could partially explain introverts and extroverts. As from what I've read, people with Aphantasia can't enjoy reading the way people who don't have it and are more out going. In extreme cases people just don't think or the thoughts just pass through their mind in a flash. People with Aphantasia are the kind of people who go to job interviews but can't visualize and think of the likely scenarios by which the interview will progress too and have to practice in front of a mirror.
This is cool. I'm a 1. I can visualize so intensely that the real world fades. I do this when exploring archaeological sites, where there is often not much above ground except some scattered stones. My imagination paints farm settlements, cattle tracks, people living out there lives. Surely this ability is what attracts us to certain fields, where visualization can help us conceive new theories.

But my memory is excellent
