Good news for the one who sees white angels at the time of death

There was a woman who, at the time of death, said to her son’s wife: Save me from these people who are wearing white clothes and have white faces; they want to slaughter me, so save me from them! How is this to be interpreted?
This is good news, as long as she saw angels with this description, for this is good news. The angels of punishment—may Allah protect us from them—are the opposite of this; their faces are black and not suitable for human nature.
