Here's my theory for what happens after you die that I came to from a dream
You are born, you live this life and all the choices you make impact your soul. You Die, there is a period of reflection your soul goes through when you can still impact the earth, some call the spirit world. When you are ready to pass from the spirit world, light surrunds your soul and beams of light come from everywhere, until it looks like you are in the middle of a star...and then, A Universe explodes into creation.
everything we are and we know is the result of a soul's journey to create our universe. That is why we are all one, and all connected.
