Why do children wake up suddenly when they dream, and they are scared when they see what they dream? What is the reason?

That's because he saw or met something that scared him without your knowledge. He was scared and didn't know how to tell you. Therefore, when he is asleep, he sometimes thinks of it, and when it rings, he is afraid. In the countryside, it is called the lost soul. Because the child's heart is already a little thing, self-control is definitely not as strong as ours. The scientific method is that you care more about him and slowly enlighten him to say it. The superstitious method is to find a fortune-telling feng shui to call the child's soul (the lost child's hair is straight and scared, look).
