Dream of screaming

I dreamt that I was walking with my friend when someone approached us and begun playing with her baby, asked to hold her then got into a bus and took her away. I started screaming but no one would help, but I did not give up. I ran after the bus until the people got off and ran after them into a slum area. We found the baby but she was different, younger, but my friend surprisedly took her, said she loved her still and started to breast feed her. What does it mean??
