As part of an obsessive-compulsive disorder, people may also experience compulsions, irresistible urges to repeatedly carry out some act that seems strange and unreasonable, even to them. Whatever the compulsive behavior is, people experience extreme anxiety if they cannot carry it out, even if it is something they want to stop. The acts may be relatively trivial, such as repeatedly checking the stove to make sure all the burners are turned off, or more unusual, such as continuously washing oneself.
Compulsion is an overwhelming unconscious need to engage in some behaviour that is usually contrary to one 's conscious wishes .
