Those are pretty simple views.

Think about if a person who died though about life.

And was like.

1) When you incarnate, you don't remember anything about this world you just are, you're incarnate, and that's the only think you can know or remember.

2) You're just a rock, and that's what happens, you don't know anything, you don't think anythink, you don't even feel, other times you can be dirt, or sand.
