i've had synesthesia for as long i could remember. i only recently found out it had a name. i've always confused it with other things and i used to think everyone had it.
i have one of the most common types, numeric/letter -> colors which is the strongest. i also have sound -> color. letters/numbers -> taste. gender/personality personification, and shapes.
i don't project the colors either, most people with the music/color thing do though. they see shapes or lines physically come and disappear. i kind of associate it, or see it mentally like in the back of my mind.
this probably sounds like a load of nonsense to somebody who's never heard of this, it's also very weird to describe.
i was just wondering if anybody else had a form of synesthesia. its always interesting to see what colors and sounds and shapes and tastes they get for certain things.
