To dream that you set up the trap for somebody else, denotes to the things in your life you are trying to hold on. Probably the relationship you are in not working anymore, or the job you were doing does not satisfy you either, but you want it hard to let go, because of the passive lifestyle. If someone has made a trap for you, then such dream indicates the fear you have of certain people or situations.
