Organ transplant patients having memory traces from donor

Claire Sylvia received a new lung and heart from an 18-year-old youth who died in a motorbike accident. She began to exhibit his tastes, habits, and thoughts. She craved foods she formerly disliked, was attracted to new colours and, unlike her usual self, became impetuous and aggressive. She dreamed of a man called "Tim L.," who (she later found) fit the name and appearance of her heart donor. She never met or new Tim whose identity was concealed from her as a matter of medical policy.
