As I stated earlier in this thread, Saint Charbel Makhlouf went into a seizure during the consecration and then died on Christmas Eve about 8 days later.
In my own life, I knew a well liked priest that when I went to see him as he lay in the coffin, he had a smile on his face. Since he was part of a religious order dedicated to Mary, I can only imagine that he died seeing the Mother of God.
On the other hand, I knew a priest who was not a very good priest when I was a boy. Another priest told me how he died, and it seemed to give him a fright to describe it.
If one recalls the story of the fig tree, and how Jesus withered the fig tree because it did not bear fruit when He wanted it to, this sounds like this priest.
This priest died on the day he retired from the priesthood...
