Gesture
Most gestures we make in dreams symbolise some inner state of being. To understand them it is best to imitate the gesture and thereby see what it expresses. For instance, there are the typical gestures of fear, anger, tenderness.
Gesture may also be a way of communicating something that is still not put into words, not clear. Or occasionally gesture or posture is a way of changing your inner condition. For example by taking a positive posture, or making a confident gesture, this might shift feelings of uncertainty. See Posture.
