Synaesthesia is a neurological phenomenon where the activation of one sense, such as hearing, triggers the activation of another, usually unrelated sense, such as sight. This means people with synaesthesia often experience additional sensations compared to the rest of us.

There are many different types of synaesthesia. Some people have auditory-visual synaesthesia, meaning they see colors when they hear sounds. Others see colors when they read, hear, or think about letters or numbers. This is known as grapheme-color synaesthesia.

People with synaesthesia don't have any control over how their senses collide. Instead, these are spontaneous, vivid experiences that usually stay the same over time.

For example, today, a person with grapheme-color synaesthesia may perceive the letter "A" as being red. And they'll most likely see it as being the same shade even years later.

I've never had such an experience, nor have I heard of anyone who has it.

One person told me the barnyard smell he associated with the color green, but didn't say he actually saw green.

Weird.
