Reincarnation vs. afterli

Corrosive, i personally dont belive in the heaven/hell bible concept. My theory is that there are different dimentions all running symoltaniously, this, ghost, spirit, maybe others too. I belive that when your physical body dies, regardless of your belifes or religion, we all go to the same spirit world. As i said before, 'your' version of the spirit world.
I also belive we can choose to stick around in our spirit world or become guides, or just watch out for our loved ones. Maybe pay a visit now and again. And of course, if our spirit is still in need of growth reincarnated when the time is right.
