Afterlife beliefs?

I believe that people who have done bad things in their life become spirits on earth in order to give them a chance to fix what they've done to whoever they have heart. I also believe that people can also choose to stay on earth when they die to watch over relatives, or someone they care about. But I also think if the family moves, then they're still stuck in that place that they decided to stay. I also think that if we did mostly good things in our life or feel bad for what we did, then we go to some sort of Heaven(Not the Christian one). I think it will be some place that's really pretty with lots of grass and streams.I also think that when I get there everyone will be able to understand the animals that live there and we will be able to communicate freely.

I belive that you go onto another life. That the first time your soul was on earth it was an animal, same for the last time.
