I don’t know if you should call that Gilgul. Gilgul is a deep concept that has to do with the Neshama. This seems to be about the same person being born again (which is what the Emunos Vedei’os addressed).
Anyhow, I know someone who did this and it sounded fascinating. Later on he started wondering if the questions and prodding created the person in his imagination. Who knows, but sure sounds like fun.
