Everybody who has it experiences it in different ways,

so I asked a handful of people from around the world about their experience.

[Male Respondent] Somewhere in my brain,

the senses get mixed together.

When I experience one, I'm also experiencing another

that is completely unrelated.

[Female Narrator] What do you mean?

[Male Respondent] I color code numbers in my head.

[Female Respondent] So, ever since I was a child,

I was able to taste words.

[Female Participant] If I'm in physical pain,

I experience the pain in color and shape.

[Female Interviewee] Sounds, melodies, and, in fact,

soundtracks also has a color to me.

[Female Narrator] What sort of associations would you make?

[Female Participator] The number three is blue.

[Female Respondent] Number three is light blue.

- [Male Respondent] Three is yellow.

[Female Interviewee] Number six is a flirty woman.

[Male Respondent] Four is green, two is red.

42 is green-red.

That's my favorite number, because I like

the colors red and green together.

[Female Narrator] But wait, it gets weirder.

- [Female Interviewee] For example,

I loved Flashdance songs.

She's a Maniac is blue one for me,

but What a Feeling is yellow.

[Female Respondent] Word people tastes like meatballs in tomato sauce.

[Female Contributor] Violins as navy blue rectangles moving from right to left.

[Female Respondent] The word English tastes like

a slice of lemon.

The sound of banjos tastes like Oreos.

[Female Narrator] Crazy, right?

But a life without it?

[Female Interviewee] Hmm, my life without Synthesia

I don't want to imagine it.

More empty.

[Female Participator] My life would be a lot more bland.

[Female Contributor] The world would be very flat

and not as colorful.

[Male Respondent] I would be bored.
