I'll try. For example, our nightly state that forms a sort of split in our stream of consciousness is similar.
It's a bit like saying you are happy life is over when you go to bed, but in reality there's a pretty good chance you'll start a dream state which you might not remember afterwards.
Still, even if you might not remember a nightmare, you don't want a form of yourself to experience it. As you know in that 'now' it will be suffering for that version of yourself.
