What scenes and symbols reveal the ending of this surreal thriller?

[LoganSP]

I just watched that new surrealist thriller that's been getting a lot of buzz, and while I was captivated by the atmosphere and performances, I have to admit the ambiguous ending left me completely baffled and unsure what actually happened to the protagonist. I've read a few online interpretations, but they seem to contradict each other wildly, with some seeing it as a metaphorical journey and others insisting on a literal, supernatural explanation. For viewers who feel they've pieced it together, what are the key scenes or symbolic details I should re-watch to understand the director's intent? How do you approach deciphering such an open-ended conclusion, and are there any interviews with the writer or cinematographer that shed light on the film's core themes without outright spoiling the intended ambiguity?
