Synesthesia is a neurological phenomenon in which one sense is involuntarily perceived along with additional senses, causing people to hear colors, feel sounds, or taste shapes. It can also join objects such as letters, shapes, numbers, or people's names with a sensory perception such as smell, color, or flavor.
