When my uncle was hospitalized after his stroke, the priest came and gave him Communion, as well as Holy Unction.
We were anticipating his recovery....however, he passed away after a few days.
The day he was given Communion he began retaining fluids and had a hard time breathing. The nurse had to suction the liquid from his stomach.
When I realized what she was doing, I asked her for the liquid that she suctioned.
She gave me this really odd look. "What?" she said. I told her that he was given Communion only a few hours ago, and I would like his stomach contents. She must have been Christian, for she then silently got an empty pill bottle and drained the liquid into it, and gave it to me.
I kept it for a few days, and then buried it with him.
