No, Sachs is writing about synesthesia, a neurological condition that causes people to "see" sounds, "smell" colors, and so forth!. The sensory inputs to the brain in these cases overlap a little, so you might hear music and at the same time see color-tints that correspond to the sounds, or you might look at a painting and smell or taste things that correlate to the colors or shapes!.

Some people report experiencing synesthesia when they're under the influence of certain drugs, especially hallucinogens!.Www@QuestionHome@Com
