Psychometry would be the easiest example of psychic synesthesia to grasp. A psychic reader holds a piece of jewelry (token object) and clairvoyantly sees dear, but dead, Auntie Mildred, while feeling her joy or anguish (clairsentient), and hearing her message (clairaudient). Or another example would be where a medium looks at a photo and immediately feels the presence, and an experience of, a departed loved one.
