Well, such as in the TV Series "Heroes" - at one point we the protagonistic character of Peter Petrelli acquire an ability that involves enhanced synesthesia. With this, we see objects that make sound (like a trash can hitting the ground) produce light/energy visible to only the ability-holder. At another point, we see a piano seemingly radiate ribbons of colour. When in actuality - someone with synesthesia really only visualises these colours and patterns in their mind and not as radiant energy existing in their environment.

I related it to being able to make out details in a scene because in the example with the piano, the ability holder was a deaf nurse - she could not hear the sounds being made, but she could see them.
