How to verify synaesthesia

Synaesthesia is a rare mental disorder, also known as synaesthesia, which means that hearing and taste are automatically linked. In the patient's sensory system, numbers and words are colored, as are shapes, textures and emotions. For example, when they eat delicious food, they will hear wonderful music, wonderful concerts and smell flowers. Green may be a lovely bear in their feelings, and sad mood may be an Aries for them. Thought is often a by-product of emotion. Passionate emotions, even if it is wind, frost, rain and snow, there will always be bright sunshine. And when the mood is low, no matter how sunny the day is, it will be like the haze in the rainy season.

Synaesthesia is an expression of neuropsychology. The behavior of synaesthesia patients is beyond the general behavior of ordinary people, such as the well-known loner, which is actually a mild mental state.
