Have you ever tasted a word, or seen colors while listening to music?

If you have, you may be among the 1% to 4% of people who have a fascinating trait known as synaesthesia.

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.
