To dream that someone is dead is to have life. Someone in your neighborhood must have recently added a family. Of course, it is also possible that the pet gave birth to a baby.
It's a good sign that a nun gives you Buddhism. Under normal circumstances, seeing family members in a dream means seeing a bodhisattva and bodhisattva giving alms.
It is a blessing. Since it is hung around the neck, it is of course a blessed person. I hope you cherish the blessings, do more good deeds when you have money, help the poor and help the poor, and accumulate merits.
