Well, for Ingrid Carey, “numbers and letters, sensations and emotions, days and months are all associated with colors”.

Bad acid trip? Mental illness? Nope, turns out it’s a legitimate neurological condition where two or more senses entwine and the result is synesthesia.

The synesthesia of those in the “perceptual” category is triggered by sensory stimuli like sights and sounds, whereas “conceptual” synesthetes respond to abstract concepts like time. One conceptual synesthete described the months of the year as a flat ribbon surrounding her body, each month a distinct color. February was pale green and oriented directly in front of her.

Richard Cytowic, a neuroscientist and author of “The Man Who Tasted Shapes” (Bradford Books, 1998), has watched the scientific shift in attitudes toward the condition in recent years.

“Many of my colleagues claimed that synesthesia was ‘made up’ because it went against prevailing theory,” Cytowic told LiveScience. “Today, everyone recognizes synesthesia as no mere curiosity but important to fundamental principles of how the brain is organized.”
