Duke Zhou:
When I heard birds chirping in my dream, a happy event was coming. Pregnant women have the same dream, which indicates that they will give birth to a healthy baby smoothly.
It is ominous to dream that a robin is singing.
Dreaming of birds singing means that your partner will be in trouble.
People who dream of pigeons singing indicate that women will have a happy event.
It turned out that the Duke of Zhou was singing birds in the air and his wife was dead. Duke Zhou dreamed that birds were singing and had something to leave. Dunhuang dream book
