Occasional thoughts about getting sick or about the safety of loved ones are normal. After all, everyone has moments of worry. When the thoughts become overwhelming, time-consuming and interfere with important activities, they can turn into obsessions.

Definition of Obsessions

Obsessions are thoughts, images, or impulses that occur over and over again and feel out of a person’s control. The person finds them disturbing and unwanted, and usually knows that they don’t make sense. They come with uncomfortable feelings, such as fear, disgust, doubt, or a feeling that things have to be done in a certain way.[1]

Types of Obsessions

People with the anxiety disorder known as obsessive compulsive disorder (OCD) experience obsessions that often have themes to them, such as the following:

  • Fear of contamination or dirt
  • Having things orderly and symmetrical
  • Aggressive or horrific impulses
  • Sexual images or thoughts

Signs & Symptoms of Obsessions

  • Fear of being contaminated by shaking hands or by touching objects others have touched
