Children
To see children in your dream signifies an aspect of yourself and your childlike qualities. You may be retreating back to a childlike state and longing for the past. You are still trying to satisfy repressed desires and unfulfilled hopes. Perhaps there is something that you need to see grow and nurture. Take some time off and cater to the inner child within. Alternatively, the dream may be highlighting your innocence, purity, simplicity, and carefree attitude. If you are fighting with children, then it implies that you are repressing your inner child. The children could represent someone in your waking life (coworker, mate, sibling, etc.) who is acting like a child. If you see children fighting in your dream, then it means that your sense of morality and character are in conflict.
To forget about your child or children suggests that you are feeling overwhelmed by your waking responsibilities. The dream is telling you that you are overly fixated on minor details and overlooking the important things in your life. You need to re-prioritize your time and focus on what matters. To dream that your own grown children are still very young indicates that you still see them as young and dependent. You want to feel needed and significant. To dream that you have more children than you actually have in real life means that you are discovering old talents or skills that you have been casting aside.
To dream that you are watching children but they do not know you are is a metaphor for some hidden knowledge or some latent talent that you have failed to recognize.
To save a child in your dream signifies your attempts to save a part of yourself from being destroyed. If you dream that you are separated from your children, then it symbolizes failure in some personal endeavor or a setback in some ideal you had.
To see children being abused in your dream implies that you are lacking a voice for your own inner child. You feel that a part of your own childhood is lost.
