A shared group consciousness must exist within a rhetorical community in order for a fantasy theme to chain out, a rhetorical vision to develop, a saga to exist, or a symbolic cue to imbue meaning. Some terms that portray a shared group consciousness are a common ground, mutual understanding, created social reality, meeting of minds and empathic communication. Once a group has reached shared group consciousness, they no longer think in terms of "I" or "me" but in terms of "us" and "we." After all, communication is the drive that allows groups of people to move towards their goal. A shared group consciousness also reduces uncertainty by allowing groups to develop an identity that shapes their culture. By shaping their own culture, this can influence norms, roles and even decision making.
