If kidnapping features in your dream, this may suggest the desire to dominate or be dominated by another person.
If you are the victim but don’t feel afraid, this could lend a sexual connotation to your dream.
If you are held hostage in a dream, this could indicate that you feel someone has a hold on you, or that you are subject to some influence that prevents you from doing what you need to do. Hostage-takers often make demands for money, personal recognition and so on. Is there someone in your waking life who is placing unnecessary demands upon you, or making you feel guilty? In some hostage dreams, as in real life, a rapport develops between the victim and the hostage-taker; if this is the case, it could indicate a love-hate relationship in your waking life. Finally, might this kind of dream not also suggest that you are held hostage, not by a person, but by your fears?
