OCD Themes is an illusion

I get what you mean, for me though I developed harm ocd and pocd before I even knew that it was OCD. My OCD was about anything that could potentially hurt someone, verbally or physically. It wasn’t until about a year or two later struggling with these themes that I realized they were OCD.

It's the brain filling in the gaps if you don't find a solution. Say for instance you see something unidentified in locke Ness, your brain will fill in a gap and see the lockness monster. Or an undignified aircraft, its aliens etc. If we can't identify the source of the stressor before our brains are able to fill the gap, then we almost feel stuck in it. The theme is usually based off of an initial intrusive thought that distresses us and will keep going back to that. My brain asks a question basically and responds You are stressed, why are you stressed? Maybe it's this thing you were stressed about before? And then bang. Theme It's usually something that strongly disagrees with our core values more than the average person. People raised strictly or with not enough discipline can lead to core values out of kilter. The more I'm moral, the more I'm vulnerable to moral injury. My themes around morals, so anything immoral immediately triggers me and I'm in a loop with that until I calm myself. It's a threat system
