Synaesthesia

"Synaesthesia is a truly fascinating condition. In its simplest form it is best described as a “union of the senses” whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together. Some synaesthetes experience colour when they hear sounds or read words. Others experience tastes, smells, shapes or touches in almost any combination. These sensations are automatic and cannot be turned on or off. Synaesthesia isn’t a disease or illness and is not at all harmful. In fact, the vast majority of synaesthetes couldn’t imagine life without it." (http://www.uksynaesthesia.com/)
