This has been in the science news lately.https://www.discovermagazine.com/mind/why-some-people-cant-visualize-images-and-may-dream-in-wordsSomething like one to three per cent of the population can't visualizeobjects. I wonder if such people can still design electronics.And maybe 10% of the population is never really in the dark. They (we)always see flashing geometric patterns, which are distinct fromhallucinations.
I wonder if that's related to not having an 'Internal monologue '. Eg; talking to oneself.
Cheers
