2. Displaced anger
In medicine, displaced anger is said to occur when a person gets angry over things that are actually unrelated to the hyper-reactivity of the person. For example, a person gets much angry over the slightest noise of a creaking door, even if he was sitting peacefully few seconds ago. This indicates that there shall be some anger-provoking memories from the past events in the person’s thoughts, which might have been suppressed and are being omitted at unrelated things.
