Decoy

Otherwise, you may be facing an important decision in dedicating yourself to a project, task, or relationship.
A dream in which you are betraying someone suggests your guilt resulting from actions or thoughts that you are not proud of.
Lie Detector
A lie detector in a dream represents a test which you are trying to pass. You may have a secret which is bothering you and you are afraid of being caught. You may also have a big interview ahead, or a final exam, which is causing you stress.
