Well, I think Our Lady of the Rosary Library has some tracts they make available for a few pennies apiece or free online that have some incidents..
And I think some of Fr. F.X. Schouppe's 'Hell' has some too, and that is on
Saints' Books.
They're worth reading.. now for possessions.. to my recollection Fr. Amorth's books dont' go particularly detailed but are more practical how to approach the problem books, good on practical, short on theory and a little criticized for a bit of it, but overall quite good and practical it appears.. Hmm.. I also have Fr. Fortea's book, not sure I agree with all that's in there.. but overall good I think. . a little less readable than Fr. Amorth's.. don't recall that it goes into specific incidents much either, just how to handle.. haven't read it all..
The earlier and Catholic portions of the Philokalia are very good on the interior warfare aspect.. I've excised tons of quotes on that matter, and they're on
Saints' Quotes in the database, and I have some reference notes and compilations on the interior faculties.. which some of pretty much repeat what Fr. Chad Ripperger wrote about in his 'Introduction to the Science of Mental Health'...
I've never been particularly into reading retelling of harrowing incidents like the one that movie was based on so I'm not someone who knows much about that niche. You might find something more on Tan Books.. Or Preserving Christian Publications.. I am not sure..
