People making fun of you

Hello. This happened today, but people in general making fun of me has been a recurring theme throughout my life, and I'm a sensitive person so wonder what is wrong with me. So. I was at the bus station sat next to some 30-ish looking guy who offered to exchange money into larger coins, when he saw me fumbling with change. He seemed eager to chat and spoke at length about his life, even though he didn't care whether I offered much input or was interested. I did try though at the beginning. We had a "normal" conversation for about 15 min. He also said he received injection "therapy" today, and I presumed it was something like an AP (antipsychotic), and I was right. He also seemed a bit spaced out or not with it.
He asked how long I ever worked for, and I said barely a year (due to my own mental health issues I didn't feel like mentioning), and said it was because I quickly got bored and constantly felt something better was waiting for me, so switched jobs a lot, and that part is true.
From then on, he started smiling or chuckling weirdly, and kept asking weird questions. Like if I read books much (chuckling plentifully and even when I was silent whilst looking at me - definitely in a mocking way), if my surname is a famous singer's surname (we share the same first name) but that he "doesn't know her", if I believe that he lived by himself when he was a small child for a year, etc. Laughing all the while, directed at me.
Even when I tried to respond, he was sort of making fun of what I said. Not being too sensitive, was very uncomfortable for over 10 minutes and he kept looking at me and laughing at me.

So my question - someone with his sort of experience/problems, why would he randomly start making fun of someone? In your exp., what is "wrong"/different with someone (child or adult) who is often made fun of? Always wondered this. Or why would someone do that? This sort of upset me and it's not a nice feeling, from a stranger. Don't think his "illness" had that much effect.
Sometimes I really think that my few friends never do this or never can tell me what is wrong with me because they're too polite or tolerant.
What is your opinion?

Also, he was sober and fine-fuctioning, was definitely not having an episode during the talk, was just a little off due to recently receiving therapy.

What you experienced is an example of a very disillusioned individual using a random person as an audience. “You can’t possibly know the trouble I’ve seen”.

While it felt like a personal attack, it wasn’t about you personally but all about his own disillusionment. It can be very unsettling to experience that. It’s more about how that person is lost in his own head and not about you. You just got to listen to a conversation someone was having with themself out loud.

People who make fun of others are insecure. They do it to feel better about themselves, but they have to keep it up, because they never feel better.

Yes this is definitely about him not you. Some people might not have tolerated him as much as you did however, that’s not a criticism of you btw, but some people might have told him to mind his own business.

The laughing while speaking to you sounds like he could have been having a hallucination at the same time. People who hallucinate often hear or see things that make them laugh inappropriately while they’re seemingly engaged with another conversation.

I don’t think he was laughing at you, honestly.

My ex husband would laugh at things.....but he was laughing at things going on in his own mind not at things I said or he would think what he said was funny when no one else did.

When you are dealing with someone who has mental illness don't assume the issue you are dealing with is about you.....most often it is their issue

I’d not waste time guessing why strangers do what they do. You don’t know him so he could be very unwell. I’d be concerned if a friend or family started acting strange with me. With strangers though you’ll never know and I’d not let it bother me.

You’ve no idea if he was sober or not btw

The example you quoted, at the bus station, is easy to write off as something that was wrong with the guy, not you. Please note that most people do not share with strangers at bus stations that they have just had an antipsychotic injection. So that is already off. Also, while it is not true in every instance, oftentimes people who are given injections, as opposed to prescribed antipsychotics in the form of a pill, are not medication-adherent on their own and injections are a way to assure that they actually receive the medicine. He might have been one of those folks. I agree with the posters above that the issue was his. However, it does not help you as you are reporting a recurrent issue. Can you write more about other instances when you were made fun of or at least when you thought that you were made fun of, and then people making fun of you were not so obviously out of it?

Dont let it worry you too much. In HS i got made fun of by some other girls because i didnt have the most fashionable clothes

They do that because you’re better than they are, and they know it, and it’s the only way they can convince themselves otherwise.

Just in general from my observations, immature people make fun of people who are different from the "norm" because they don't understand the difference. Being made fun of is NEVER comfortable but I have also noticed that when one has a lack of self-confidence it hurts even more. I saw how that struggle effected my mom throughout her life.

Then you have comedians that take that being made fun of & make it into their business & way to earn money by making their experiences into their comedy
