Lie Detector – If you dream of going through a lie detector, this indicates a feeling that someone in your life does not trust you to tell the truth. This is a saddening revelation, but one which is nevertheless true. If another person in particular is connected with the lie detector test, this is probably the person you feel does not trust you. On the other hand, if there is not another person involved, this may indicate a judgment you are passing on yourself. Perhaps you are a habitual liar, or perhaps you know you have been telling lies about a particular situation and are afraid it is going to catch up with you.
