Booming post, Old Lunch.
I don't recall viewing the ending as ambiguously as you did, but I find it easy to ignore a most post-Code 30s and 40s films' endings (e.g., Lang's Ministry of Fear which I just watched and ends with an absurdly cheerful wedding preparation joke between two people who should be psychologically shattered by their recent experiences).
I'd add the opening segment where Marshall and friends stumble on the bathing women to the setpiece list. Totally dreamy, which seems like a purely aesthetic choice at first but then makes works perfectly as that meeting story becomes the child's bedtime myth version of his parents.
