I recently read about this neurological “phenomenon” called Synesthesia.
It’s not a disorder or disease, it’s more of a way of looking at things.
It’s a perceptional phenomenon that is quite fascinating.
Certain people will perceive certain letters or numbers as colors and certain people will percieve different musical tones and sounds as colors.
I do the latter.
I’ve always had a “That sounds a bit purple” type of feeling when I hear certain noises. I also do it with smells and days of the week.
For example, Wednsday is a brown day.
And coffee smells red to me.
I always assumed that everyone did this.
It’s not a voluntary thing, it’s more of an association that makes telling things apart easier. That’s why I can notice the differences in sounds and music so well and I rarely lose track of the day of the week.
Pretty interesting stuff, huh?
