Is that one of those things where you associate numbers/letters with colors and wierd stuff like that? If yes, my teacher and her siblings have it (she spent a whole day talking about it). If not, please explain what it is for me and what your synesthesiacs are.
Synethesia covers a big range of conditions where two (or more, I guess) senses overlap. For example, these two guys see and feel weird stuff when they listen to music.
[6:53:35 PM] Someone: you know, you and I almost never disagree on music taste, and we both have synesthesia, is this a coincidence?
[6:54:16 PM] Person: and our descriptions of syn
[6:54:23 PM] Person: when listening to music are similar sometimes
[6:54:37 PM] Someone: our syn is fairly similar, mine's just more textural than yours
[6:54:52 PM] Someone: and I think yours is a little more visual than mine
[6:54:53 PM] Person: yeah mine's highly visual and spacial
[6:55:15 PM] Someone: I've got fairly strong visual, but textural is first
[6:57:35 PM] Person: mine is almost all visual and spacial
[6:58:13 PM] Person: maybe we should inquire as to the music tastes of other people with syn
