The funny thing is I’d been working as a GP for more than 30 years before discovering there was a word for the way my brain worked. One day, while doing some research into managing anxiety for my paediatric patients, I stumbled across some research from Macquarie University in Sydney about grapheme-colour synaesthesia. Other people were similarly affected, apparently. Then I learned about another common form of the phenomenon, called spatial-sequence synaesthesia, which fitted with my experiences of not only seeing time in a 3D pattern but numbers and letters too. Perhaps I was not so odd after all.
