Handcuffs are a binding symbol and spiritually would suggest that we are being hampered, probably by our own doubts and fears. If we are putting handcuffs on someone, we may be attempting to bind that person to us and assert our supremacy over them or what they represent in the dream. We may be being overly possessive. Dreaming of being in handcuffs denotes that we have been restrained in some way, possibly by an authority figure. We may ourselves feel that we need to be more circumspect. 'Joke' handcuffs are often taken as symbols of marriage or committed partnership. In dreams their deeper meaning may signal some doubts about the relationship.
