It has been known for people who have organ transplants (especially vital organ - kidney, liver or heart - transplants) to take on personal traits of the donor. There is a recent example which featured in my local paper around four months ago, of a man who had never liked cooking before he had a major organ transplant. When he recovered, he found a fascination with cookery, and was actually quite good at it! It's also been reported numerous times of transplant patients who have been no good at drawing, and when they recover, they discover they have a flair for art.

There has to be some logical explanation, maybe a second chance at life drives patients to try new things and make the most of their lives, and have always had a dormant ability or an innate interest in their apparently 'new found' hobby.

But as for feelings for another person that the previous owner (for lack of a better word :S) goes, there is no evidence to prove this.
