The inability to recreate senses in your mind.
I'm asking because I know 4 people with at least some form of it, and we're all ND.
MY bf is adhd and has complete aphantasia, can't imagine any pictures smells etc in his head.
I'm bpd, cptsd and I can only see images, no sound, no tastes, no feeling or smells
Autistic friend can recreate sounds but nothing else.
Second autistic friend also full aphantasia.
Seems most common in neurodivergents so I was wondering if anyone else has it lol
