There are some things too incredible for our petty human minds to comprehend.

When my friend Lisa's little girl was 3, she talked about her "other brother" and her "other grandpa." It freaked Lisa out.

When I was very small, I was fascinated by pictures of Native Americans in one of my brother's books. It was as if I had known them. I can't explain that now.

And sometimes you meet someone you've never met before, and it's like you've known them forever.

I took to playing the violin very easily, as if I had done it before. One time when I was practicing, I got frustrated with the music, and the thought popped into my head, "that's not how I played it before." But it was a new piece, one I didn't know.

I can't say with complete certaintty that I believe one way or the other, but I can say I certainly believe in the possibilities.
