What does it means when dreaming that one's own infant died?

The meaning of this dream could depend on the dreamer's actual situation; it would mean something different to a pregnant woman than to a parent of an infant, and something else entirely to an adult with no small children, or to a young teen. Very generally, the "infant" might represent an idea, task or project in which the dreamer is deeply involved. In this case, the dream represents fear that the project will fail.
