Dream About Mom Panic Evacuation Kidnapping

This isn’t my nightmare, but rather my mom’s. She said that everyone was evacuating for a reason she couldn’t recall. She was with me and my little brother. There was a lady that was trying to convince my little brother that she was my mom’s friend. She was trying to take him. He was starting to believe her, despite my mom being right next to him ( she was telling him that the lady wasn’t her friend, but for some reason he couldn’t hear her.) She then woke up in a panic thinking that my little brother had been kidnapped (She was able to figure out it was a nightmare quickly)
