For example, I see all the letters and numbers in different colors. Zero is white, six red, four blue etc. And this never changes, the colors relating to a special thing is constant.
Sometimes I see some sentences, words or names in color too. Musical bands, movies, they all come in different, own colors.
To extend the description of my...eh, ability (?)one level, I play drums in a band, and for me, all our songs have a specific form in my mind. Some songs are more edgy, some have a rounded form. Some are dark, some light. It all projects itself like pictures in my brain.
I heard that Kandinsky, the painter, experienced musical color-cascades when hearing Mozart or Brahms, so he painted his visions, which accord to my taste completely.
I donīt hear music or experience taste in the way I apparently experience color and in some way, form.
It would really be interesting discussing this with someone who experiences Synaesthesia.
