The key feature here is that the compulsions actually reduce our mental stress. So engaging in the compulsion, whether it's a physical compulsion of like, you know, turning on and off the stove seven times, that's a really classic thing. Or arranging things in a particular way, or sometimes we forget that compulsions can be mental in nature too. And then what happens is once we engage in the compulsion,. then the obsession kind of calms down, relaxes or goes away.
