Oh yeah, I remember learning about that in mental health class in high school! I always thought it was a fascinating concept. Not to mention it suggests, at least to me, a high level of creativity and a very...how to describe it? An open spirit, a more wide-ranging way of seeing the world.

I sometimes get vague color impressions of things, though usually I would have to think about it a bit to decide what color something sounds or smells or tastes. And usually there's an association with a color we generally see as going with that sensation. For me it's more of a way of describing things in new and interesting ways, rather than how I automatically see things.
