Metal Detector – A metal detector is a symbol of being examined and scrutinized, often to the extent of invading your sense of privacy. There is usually some tradeoff for this scrutiny, or some perceived reward for letting yourself be examined and judged. If a particular person is associated with this dream symbol, it is an indication of a lack of trust between the two of you. If you are the one being subjected to screening, it indicates that the other person does not trust you. On the other hand, if you are conducting a screening of the other person, it indicates that you do not trust them, or that you should not. The outcome of the metal detector screening is significant as well. It gives insight into whether the distrust is warranted or not.
