synaesthesia When I was in truth young, I see a recur day-dream that I was staring, entranced, at a diffused ashen flower. It was bid secret code I had seen or see in my open-eyed life, because the pristine, thinly-veined petals were much(prenominal) an bonny subterfuge that it manifested itself upon my ambition creative thinker as a trick and a sound.
