To dream of duct tape represents certainty that something in your life “stays put” for the interim. Your strong hold or grasp of some temporary situation. A strong need for certainty that a situation won’t change in the interim. You may be desiring to notice or feel permanence in a situation or relationship until you have a better solution.
Negatively, duct tape may reflect temporary solutions to serious problems for which you have no resources to fix with serious solutions. Holding together a crisis with no permanent solution. Temporarily hiding impotence with all available resources to avoid embarrassment. Temporarily measures being taken to avoid being discovered doing something wrong or illegal. Irresponsibly controlling a serious problem situation with temporarily solutions.
