condition where the senses
in the mind
, causing a situation
where things that stimulate
one sense can cause the others
in ways also. This can also affect
other parts that depend
on sensory data
, such as the part of the brain
that handles language
People with this condition (a synesthete) commonly see letters as being of various colors, see shapes when they hear sounds, or hear sounds when they are touched. The correlations between the senses vary from one individual to another - while one may see a letter "e" as a deep red, another may see it as white.
Personally, I am jealous of those people with this condition. While I am aware that it can be an inconvience at times, the additional life and depth the world would have seems to be a very attractive idea.
