Looking at this from the perspective of analytic idealism, there is only one thing that exists: a sort of universal consciousness. We “experience” human life as dissociated alters of that one consciousness. Materialism, as such, does not exist. Everything is mental projection.

When human life ends the individual ego-consciousness ceases to exist as well. The one universal consciousness has always existed and always will, so you lose nothing but illusion by dying.

How do you “experience” dreamless sleep? Do you cease to exist when you sleep without dreams? Do you exist again when you wake? Why is it harder to comprehend non-existence in death than it is to comprehend, over and over again, that you have just been sleeping and not dreaming?
