I liked the jacaobs ladder view on demons.

A soul trying to cling to its old life will feel haunted but one that is at peace Will see them as angels.

Quoting top comment from youtube:

14th-century Christian mystic, Meister Eckhart:

“Eckhart saw Hell too. He said: ‘The only thing that burns in Hell is the part of you that won’t let go of life, your memories, your attachments. They burn them all away. But they’re not punishing you’, he said. 'They’re freeing your soul. So, if you’re frightened of dying and … you’re holding on, you’ll see devils tearing your life away. But if you’ve made your peace, then the devils are really angels, freeing you from the earth.”

You don’t have to have a literal hell to know for yourself the truth of Eckhart’s insight! Tremendously deep movie.
