Ruler، To dream of a ruler represents a careful analysis of a situation or other people. You may be examining, observing, or comparing something. A ruler could also represent measuring how powerful, valuable, or important something is.
You may also be considering a number of factors before making a decision, or double-checking something.
If you attack something in a dream with a ruler it may reflect your objectivity or criticism of a problem. You may be confronting a situation by examining all possibilities or weaknesses.
