Children signify many things in a dream such as wanting to accomplish long repressed desires and wishes. The child in your dream may also be your inner child. Your inner child may be telling you that you need to grow and be nurtured. They also represent innocence and a carefree attitude.
If you have children and you dreamt that you forgot them, then you may be overwhelmed by too many responsibilities. You need to make time for yourself and reprioritize. Dreaming of children also signifies your need to be needed and important to someone’s life.
If you are saving a child in your dream then you are protecting your innocence. You are doing what you can to protect who you are. Also, being separated from your children symbolizes setbacks you will have in an ideal.
