What you've said makes sense

Without realising it, my beliefs have kind of changed. My thoughts are that when we die, our "energy" or "soul" is released. Where it goes I don't know, maybe another body like reincarnation, maybe a "source" as L&B has said.

I still don't like the idea of burial. I would still go with cremation (I too am terrified of being buried alive!). But I'd like my ashes to be buried, with a tree or something, because I'd still like to nourish something that way.
