The voice in your dream is a feeling of your own subconscious.
He said you only have 15 days to live.
It actually reflects your own anxiety.
This anxiety comes from time. You may realize that time is pressing, precious and short, and find that you have not finished many things.
So I will have such a dream.
Many people have had this dream. In the dream, it seems that someone is announcing how long he can only live or when he will die. There is nothing to worry about. The reason for this dream is psychological, and I am worried about wasting my time.
