I am not sure whether I am. Would love to find out.
If you sense numbers as colors, or see images when hearing a tone, you might be a poet and don’t know it.
Atypical and subjective responses to colors, sounds, numbers and the like are caused by a neurological condition called synesthesia, a mutation in an area of the brain that can result in a cross-wiring of hearing, vision and touch senses. According to neurologist Vilayanur Ramachandran, synesthesia is eight times more common among creative people such as artists, musicians, writers and poets. (It affects a small portion of the population.)
“What’s really going on (is that) concepts in different parts of the brain are cross-wired in some people, resulting in a greater sense of metaphorical thinking.”

I was listening to a TED Talk by Vilayanur Ramachandran: A Journey to the center of your mind today. He illuminates the subject of Synesthesia and gives one possible explanation of why artists may be more synesthetic than others. The topic of synesthesia occurs towards the last 30% of his presentation. He even shows how we are all synethetic with a simple experiment.
