Starstruck
You did not describe how you felt when you told her, "No one, I'm by myself."
How did you feel?
Most likely, judging from the title, you feel lonely. It is that simple. Your mind has not caught up to this fact, so your heart is trying to send a wakeup signal via the dream realm.
The childbirth is a representation of a new beginning for you. A new chapter in your life where you are spiritually independent. You will not
need nor depend on a man to feel happy. This does not mean you are going to be alone. You can be independent and still be married!
On the other hand sometimes dreams are also more literal messages of what is to come. Maybe you really are going to be pregnant soon? Are you in a relationship? Not much background info in your message.
Be well and take care. If pregnancy does come about, you will be a strong woman for that child, whether a man is beside you or not. I am sure of it!
