Strangely Evaporated

I first heard these words in the context of a dream.

A woman (me, not me) was with her friend in the midst of a snow storm. The friend died, peacefully. The woman looked at her and thought, she doesn't look like herself. She looks strangely evaporated.

It reminded me of my father when he died. He didn't look asleep. He looked...absent. Strangely evaporated.
