Right off the bat in getting the feeling of an older type of documentary with its grainy weathered look and even a bit of the Old Hammer Films lead up to actually showing the film.
We've got the feeling of dread to come into our primary characters and also a bit of folklore but nothing as wonderful as Paganism, more along the lines of those who carry the casting out of the Most Beautiful Angel of Heaven Lucifer.
We appear to be in an unknown Suicide Forest, and they're doing a rather nice job of keeping the atmosphere Creepy as all Hell and wonderfully tense. Is what we create truly ours, or could something be Whispering in our minds without us even feeling coerced in the slightest.
I will say this, having a brain injury that messes with your memory has a very particular upside, movies almost always feel new or have a bit of deja vu, so i guess it works as I've forgotten how much I enjoyed the journey this film takes you on. Please Don't come into our looking for Gore and flashy cgi or even flashy special effects.
