Help me, what does this mean?

When a person dreams in color it means they are seeing a little into the future. The colors you mentioned were very vivid. When you dream of births and having babies it means you are starting a new chapter or beginning in your life. So I would interpret your dream as in the very near future there will be a major change, such as a move, or you will be going to a new school perhaps. Since many people were having these babies I would guess the whole family is involved. Write your dreams down whenever you remember them and keep a dream journal. After about 6 months go back and re-read what you wrote. You will be surprise how many of the things came true.
