To dream of a measuring tape represents your attempt to measure or feel the strength or severity of a situation. Noticing exactly what you need and nothing more. Doing something to test a person or situation to feel how powerful or capable they are. It may also reflect a comparison you are using to notice how bad something is or how strong something is. Doing something to see how you measure up. You may be trying to figure out why someone else can get away with something and you can’t.
Alternatively, a measuring tape may reflect your preparation or research before doing something. Figuring out how much emotion, aggression, or work will be required to reach a goal. Negatively, you may be doubting yourself or trying to see what you can get away with.
