I'm a lucid dreamer and I go around asking dream entities about the afterlife. Here are my results so far:

>a self-described "siren angel" singing beautiful music
>an angel saying I would get a hug from her
>a man saying the afterlife is a "game"
>a man saying the afterlife will be "17,000 years of fun, and then 'something' will happen"
>a man said the afterlife will be full of "Sabbath music, and Sabbath Hollywood".
>a boy pointed to the sky and said "You go to Heaven."

I did have one scary dream where my brother told me "You're a terrible person. You're going to the underworld" But I hope that was just a demon...
