Personally, I have no idea what happens after death.

I had a dream about my great grandmother, whom I've only met once right before she died. Several months after, I had a dream about riding on a train with her. We didn't speak or have any conversation, but I knew we were riding together somewhere. We got off at a stop. Without speaking, I looked back at her and she gave a nod, almost signifying that this was where we part and we walked in opposite directions. My grandmother and mother cried when I told them about this dream. They said she was my guardian angel after that.

I love the idea that some end up watching over us and keeping us safe.
