Which is a condition that happens when a sense (e.g. sight) triggers another sense (e.g. smell)?

Great info

I'm a poet, and for me the different vowel sounds have something like colours (which helps me write more euphonious lines). So do numbers and days of the week.

I have this condition & it can make everyday events quite interesting especially when you're having "an episode".

I wonder if this is what causes the smell of toast that sometimes precedes a migraine headache.
