I will take the chance to speak about the "NDE itself"; because that will lead to my answer to your OP.
I did read about NDEs containing hell; but I think all of it is a product of somebody's own mind, nothing is "real" until you are actually dead and gone with no chance of coming back alive.
I prefer to call "NDE" with "brain static" instead; you're just seeing images you either pictured once or came up from the contents of your brain.
That's why different people see different things depending on their culture or personal religion.
