Looking at all the options allows us to know the right time to act.
When Mantis appears to you carefully consider all the angles, look at things from a broad perspective. Take quiet time for meditation and reflection. When the right moment to act appears you will know it instinctively.
A Mantis in your dream can indicate that you feel victimized or "preyed upon" by others. It can also symbolize the need to blend into your surroundings or to camouflage yourself.
