The motive of kidnapping in a dream represents that a dreamer is deprived of the qualities or traits of a certain person who is kidnapped.
Kidnapping in dream is about not being able to access to a certain person. When somebody is kidnapped, that means we cannot approach to qualities he/she has.
Kidnapping is a common symbol in the dreams of parents who fear for the safety of their children. But it might also bring about their disappearance of a child within themselves…and becoming too serious.
