OCD can be divided into several categories. Intrusive thoughts fall under, what Abramowitz et al. (20101called taboo categories.

Types of intrusive thoughts


If you believe that thinking something makes it more likely to happen or that simply having the thought is practically the same as carrying it out, this is known as thought action fusion.

Having intrusive thoughts does not mean that you are a bad person. The thoughts are in fact obsessions and are part of OCD.

Thoughts can create feelings in your body, but that does not mean the thought is true.

Thoughts feel real.
