Grey Mantis in dreams
A patient, predatory insect — stillness so complete that the prey arrives on its own.
How grey changes the reading
Grey colour layers ambiguity onto the symbol. The base meaning is still there, but the dream is saying you do not yet have the colour information — the situation has not declared itself.
The base reading of Mantis
A mantis in a dream is the dream's image of stillness used as a weapon. Mantises do not chase; they wait, fold their arms, and let other insects walk in. The dream brings the mantis when you are dealing with — or being — someone whose great move is to do nothing and let the situation deliver the result. A mantis still on a leaf is the dream telling you the patience is working. A mantis striking is the dream marking that the patient phase is over and a fast, self-contained move has occurred.
