Dreaming of any type of gauge can personify self limiting behavior. A barometer measures pressure and can symbolize a grudge that needs to be released. A thermometer in a dream can be a symbolic representation of not acknowledging how you feel or how your real feelings are leading you to be reactive. You take your temperature as a way of checking in with your feelings. Gauges can also be a representation of how you measure your accomplishments in terms of life stages. If the barometer or gauge is faulty than the message would be that your assumptions are not correct. You may have categorized or dismissed a situation that is causing the buildup of resentment.
