Synethesia

In my anomalous experiences class we are currently discussing Synesthesia, a neurological disorder where one sense can cause an involuntary reaction in another sense.  Through this disorder, people can taste sounds, hear with their eyes, etc.  It's an incredible condition that only recently began to get attention in the last 2 decades.  Usually developed as a kid but can come about through head trauma, there's even a theory that every kid has this as their senses are developing, and only a small percentage of kids retain this disorder, or ability, depending on how you look at it.  It doesn't effect every day life that much for people who do have it, and it can even be helpful in certain situations such as numbers.  I think it's incredible that the brain can twist our senses together in any combination.
