Many theists claim they have an advantage because of their faith when they are dying because they believe?

All religion in general causes hallucinations. Believing in things like gods, ghosts, spirits, psychics, prophets, big foot; those always require hallucinations. Otherwise you just have common sense and what fun is that?

Your visions are of God trying to get in touch with you. Have you accepted Jesus as savior yet? The shadows could represent demons wanting to take you.

The Holy Spirit of God will draw you by making you feeling guilty. The devil will do that too. The devil is the accuser of the brethern( born again christians) The blood could represent two things.

That you have blood on your hands because you are a murderer (sinner, same fate as a murderer= death) or that you have been washed in the blood of the lamb. Ask Jesus to come live in your heart. You won't be disappointed.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
