> the word would appear right in front of him in his mind Could that be somehow related to synesthesia? Not long ago I've read: "Wednesday is indigo blue" by Richard E. Cytowic and David M. Eagleman. Super interesting book and topic even if you're not into cognitive sciences. The book goes in depth how synesthetes radically perceive one or more features (sound, vision, taste) in "strange" ways compared to non-synesthetes. Highly recommended read though.
