No, Diajin, I haven't read that book. But as to the other question you asked, I don't see why a 'reincarnate' couldn't be reminded of who he once was by people or things around him. I have heard quite a few stories about children who suddenly start speaking other languages or know about people and places that they have never been to before. I even remember one story about a child who told her mother that she was once (someone) and lived in a certain town and died there. When her mother checked it out, it was all there, just like the child had told her.
I just wish that I had some first-hand experience so that I could prove it to myself. The closest I can come is that I had 'flashes' of 'past' lives in Egypt and as an American Indian, and for all my (present) life, I have been fascinated (near the point of obsession) with these two groups of people.
