Kerry, I think all that you talk about is possible. My experiences are limitied, though, that's why I'm curious.

My mom has been my intercessor for sure. I talked to her at her gravesite a long time ago when my daughter was in great peril. The problem was resolved and I know it was God that changed the situation, not my mom... but I never really prayed from my gut like I talked to my mom. It's still one of those "out there" mysteries to me.
