In the context of Freud's defense mechanisms, Darin's inability to recall the accident best illustrates "repression".
Repression is a psychological defense mechanism that happens when a man reliably pushes away an especially excruciating or irritating idea, memory or want trying to keep his or her psyche in an increasingly pleasurable, less on edge state. The wonder was first found and speculated by the renowned psychoanalyst Sigmund Freud.
The theory holds that in spite of the fact that these excruciating musings are out of the cognizant personality, they definitely stay in the oblivious personality and regularly lead to psychological issues.
