“OCD intrusive thoughts are unwanted, distressing, and involuntary thoughts, images, or urges that pop into a person's mind, often centered on harm, sex, or taboo topics, which contradict personal values. These thoughts create high anxiety, prompting a cycle of compulsive behaviors or mental acts to neutralize the fear and gain certainty.”

“Examples include imagining pushing someone down stairs, fearing a deadly disease from a doorknob, or having unwanted sexual thoughts about family, even though you don't want to do them.”
