This afterlife sucks.

What exactly is "pure energy"? I'm familiar with "energy" but I'd love to here what this pure stuff I say lol about. Is it a Supernatural form of Energy?

How does this process of Reincarnation work exactly? and I what is the mechanism by which it happens or not, depending if the person wants it or not. I'm presuming that this is another Supernatural process, but I'm fascinated to know if there are any attributes attached to the proces. For instance, do I die first, and then use my dead brain to decide if I want to be reincarnated? or do I make that decision just before I die? Am I being a little too specific in my questioning. Is this one of those instances when one just needs to have Faith that it will all sort itself out in the end?

@GilesD I don't know the details. These were a number of studies done by researchers who only interviewed children 2-6 yrs old worldwide who remembered past lives of people they'd never met, sometimes people of different cultures and languages. Some of the kids retained the past life language, habits, food preferences, prejudices, etc., despite the shock and disapproval of their current families. Researchers always confirmed the details from the memories.
