Imagine what life would be like if every time you hear the sound of a robin, you instantly taste salt. Or you hear someone’s name, and the color blue pops into your head. Or, when you hear the sound of the ocean, the taste of apples overwhelms your taste buds. Or, you rub your hands over gravel, and taste pineapple. Or, imagine this: You’re out for dinner with with two other people, and one of them touches the other—and you feel the touch, as well. Welcome to the weird condition called Synesthesia.
