There is a fantastic website
http://www.near-death.com
It has a lot of near death experiences you can read.
There are also two books by a fellow named Michael Newton that you might find fascinating. He was a hypnotherapist who stumbled upon "lives between lives". Some of his patients talked about what they were up to after they died so he started specifically looking into it. It's been awhile since I've read them but it talks about soul groups, how we choose our next lives etc.
Congratulations on the huge achievement of changing your life and moving it in an entirely new direction. It could very well be one of the main goals you came in to this lifetime to do!
