Before we begin:
Synesthesia is a condition in which one sense (for example, hearing) is simultaneously perceived as if by one or more additional senses such as sight. Another form of synesthesia joins objects such as letters, shapes, numbers or people’s names with a sensory perception such as smell, color or flavor.
At first my wife and I found out that I was unique because I very clearly saw colors cascading in front of my eyes whenever I heard music, and sometimes other sounds like the sliding of a shower curtain or the squeaking of a door. This is how it began.
Story goes, my wife and I were in the car listening to a song and I said it was a very blue and some purple colored song. She asked what I meant, and I said, “ya know, the song is a very blue song; the colors of it.” I kept casually explaining to her about what the song “looked” like. I was completely shocked to find out songs aren’t visual/in color to other people after that. Right on the spot I even showed my wife a playlist I have in my phone called Moonlight Blue.
I still ask myself, “if people don’t see sound in color, is it just black & white then?
Sound-to-color synesthesia is technically called chromesthesia, which is all I really thought I had “different” about me at the time. Come to find out years later, not everyone sees numbers and letters as colors like I do, either!
In the end, it’s sad that not much research is done regarding synesthesia and most doctors won’t diagnose it either, because they don’t believe it’s real…
