Many people diagnosed with Obsessive Compulsive Disorder (OCD) engage in repetitive ruminations or intrusive thoughts. Ruminations consist of a sustained line of thinking about a particular metaphysical, philosophical, or religious subject or question. Such ruminations involve an extensive line of thinking without producing any satisfactory results. While engaged in such activity, a person will seem pensive and detached.
Some intrusive thoughts include horrible ideas of harming others violently or sexually. Equally repetitive, people with OCD find themselves living in fear of losing self-control. Despite that fact, they do everything in their power to destroy these thoughts and prevent them from recurring, because the ideas are abhorrent to them. As a result of these feelings toward such thoughts, however, the individuals are unlikely to carry them into action.
The compulsive aspect of OCD can be equally punishing and burdensome. Many much find it necessary to check and recheck the stove, doors, numbers, and other things for a specific number of times out of fear that without doing so he/she might be unable to prevent certain tragedies from happening. Though these behaviors might seem redundant, silly, or laughable, for the sufferers, these irrational compulsions are great source of their distress.
