Feeling Colour

Iv heard of a kind of mental illness ( allthough its not really an illness) where people taste ( eg) sausages when hear the word " computer" and stuff like that.. and hear a toilet when they feel somethi rough just random things like that and there are other wierd types of it like that but i cant remember its name. It could be a extremly advanced version of that, with a slight hint of paranormal activity?

That girl is so cool!
