According to psychoanalytic theory, emotional disconnection can be dangerous. When people deny their innermost negative feelings, instead of protecting themselves from their impulses, they may be doubly in danger of acting out on them. If powerful feelings are repressed, they may burst out in a less controlled fashion at another time. Although this is a gross oversimplification, it can be understood via a simple metaphor of a boiler that has a safety valve. If the pressure builds up, it can be released in a controlled manner. However, without the safety valve, while the boiler may be able to contain the mounting pressure for an extended period of time, it will eventually blow up.
