In psychoanalytic theory, a defense mechanism is an unconscious psychological mechanism that reduces anxiety arising from unacceptable or potentially harmful stimuli. They are the brain's ways of keeping us safe from fully aware of unpleasant thoughts and feelings. They may result in healthy or unhealthy consequences depending on the circumstances and frequency with which the mechanism is used. Sometimes, we can choose to use certain defense mechanisms.
I'll keep on posting about the most common defense mechanisms with living examples along.
