Worrying arguments in my head.

I have reached 80+ days. Since before I started my NoFap journey I've had imaginary arguments where I verbally fight with people I don't even know or people I don't like much.

Let me give you an example: the arguments would start with a typical scene where I need something from some stranger, for example, in a public office. I ask something or give paperwork that was required of me. Then the stranger would look at the paper and start criticizing me. He would list everything that I did wrong and how I can't do this or that. Then I would imagine my reply(and this is the REALLY SATISFYING PART): I would talk to him in such a way that he feels like shit and would belittle his life in front of his colleagues. I start putting him right and question his whole life. How stupid his worldview is and how he will suffer as a result of his overblown confidence.
This person would typically fit some kind of stereotype: an overconfident person who always talks about himself and is the center of a group, a banker or insurance agent who tricks gullible people or just some idiot who doesn't share what he has plenty of.

I don't know if this happens because PMO changed the structure of my brain since I was 13 or if it is some kind of subconscious conflict I haven't dealt with and it really scares me because I think this is the reason that I don't have any interest in talking to strangers and meeting new people. Whenever I made new acquaintances, it was because the situation demanded it (introductions from friends, new colleagues, etc.)

Please someone help me understand this, I have never had any mental issues and my friends would never imagine me to be like this. They simply know me as someone how doesn't talk much.

 

What I mean is that I do something alone like driving or showering and, out of nowhere, these hateful thoughts suddenly appear in my head where I imagine other people criticizing me and how I would react in a hateful or even physically violent manner. The whole argument is really vivid in my head like a scene I remember from some movie. I don't know how to reduce this or what this even means. Would meditation help?

 

Thanks for your advice, I appreciate it. Is there something I can do to handle these thoughts once they appear?
