What was the final shot really saying: memory or dying mind hallucination?

[MatthewC]

I just finished watching the movie and I'm still turning over that final shot in my head. Was the character actually seeing a real memory, or was it just a comforting hallucination his dying mind created? I can't decide which interpretation feels right.

[Jonathan.T]

I felt like I was watching him reach for something real, and part of me wants to call it a memory, even though the film has a soft, unreal glow.

To me it seemed more like a gentle hallucination that makes his fear feel human, with familiar faces popping up just enough to soothe him.

I kept going back and forth, wondering if it happened or if I just wanted closure, and it left me unsettled.

Is the real question whether the ending is about saving ourselves from grief, or about what counts as real in a moment like this?
