> On the spiritual side, I think it is somewhat calming. I face this at times when you have patients that pass away and you talk their families; you have to be the bearer of bad news. Right now, we don't know anything about what happens to their loved one’s brain when they're dying. I think if we know that there is something happening in their brain, that they are remembering nice moments, we can tell these families and it builds a feeling of warmth that in that moment when they are falling, this can help a little bit to catch them.

I do not see any connection between this and spirituality. I also see no reason to think that they must be remembering nice moments. It is possible to be remembering painful moments. This seems especially likely in cases of PTSD.

Spiritual perhaps in that it satisfies a need that cannot be provided by material comforts or by the mere intellectualising of it?
