Humans are so complicated, it's basically impossible to explain everything we do. It's what makes our world so interesting, but scary at the same time. Like, sometimes our complicated feelings and actions aren't that serious in the grand scheme of things, while other times they might hint at something far more significant.
Let’s take a look at some personality traits that might come across as a little creepy due to their oddness. While some of these quirks are harmless and just part of a person’s uniqueness, others could hint at something more unsettling. We’ve gathered a list of such traits for you to check out so let’s dive in, shall we? Just don’t take things too seriously, OK?

Sometimes I rehearse certain conversations in my head, and I’ll make the facial expressions and sometimes even say the words that I’m thinking about, so it looks like I’m talking to myself when really I’m just hoping not to f**k up another social interaction. I have gotten some *weird* looks for this when accidentally doing it in public.

True crime is among the most popular genres of media people love to consume nowadays. For instance, back in 2021, 57% of Americans said that they consumed it, which is a pretty high number, isn’t it? 

If you aren’t among those who enjoy this kind of media and are confused about what it even is, don’t worry, we’re here to enlighten you. In a nutshell, true crime is a non-fiction work, where a crime (thus the name) is examined, including the people associated with it, those affected by it, the perpetrator's motives and actions, and the consequences – everything. Also, commonly, it is about rather violent incidents, such as someone's life being taken away.

I let the spiders that live in my house and on my porch alone, IF I don’t see any bugs. If they don’t do a good enough job catching the bugs, I give them 3 warnings until I kick them out to make room for more sufficient spiders.

Sometimes I just sit in the dark and think in my living room. My wife walks in and sees me sitting there on the couch, hands on my knees, just staring at nothing in particular ahead of me.

Some experts say that people are drawn to these stories because that’s how our brains evolved. Ever since our hunter-gatherer days, we have been wired to be attuned to criminal misdemeanors – who, what, when, and where – just so we can better protect ourselves and those we care about. 

The same reason applies to why true crime’s audience consists of more women than men. By consuming content about crime, they observe male perpetrators in order to be more aware of their methods, signs of abusive behavior, motivations, and all other red flags that signal a danger to them.

As a child, my dad, who was in the military for 20 years, taught me one self defense, which included twisting someone’s arm behind their back and up to stop them from attacking you and basically detain them painfully but without permanent damage.

My 7 year old self decided I would twist my own arms behind my back like this so that my shoulders and arms would have the flexibility for this to not work on me if anyone did it to me.

I kept this up for years and now the only handy part of it is that I can lotion my entire back without help if I want to because I can reach all of it.

Speaking of red flags, today’s list is full of traits some netizens think might signal a bloodthirst in some individuals. All of them weren’t listed at random; they were answers to a question on r/AskReddit: “What’s your ‘serial killer trait’ that (hypothetically) would make everyone say, ‘We should’ve known’?”

While these signs can sometimes signal some trouble within a person, we felt the need to mention that everything should be taken with a grain of salt. After all, we don’t know the full picture of why a person acts this way, and usually context is crucial. So, don’t worry if you find some trait of yours (or someone close to you), it’s just entertainment

My friends have long said the only reason they know I’m not a serial killer is because every time one is found everyone that knew the killer says “we had no idea” and all my friends would have to say “we totally expected this”.

At night my bedtime routine is taking a shower, putting my pajamas on, then I turn on my bedroom tv. I then stand in front of my tv watching YouTube or Hulu like it’s a giant iPad for at least an hour, sometimes 2 hours. My close friends think it’s insane. I love it though.

Of course, staying alert about red flags isn’t the only reason people love true crime. Some of them are just curious about what the killers were like as people. Again, bringing this back to the beginning of our species, we had an instinct of curiosity, which let us keep discovering new things to satisfy that itch in the brain. 

Apparently, the brain rewards itself when curiosity is pursued. The reward is a dopamine rush, which makes you feel happier and more inclined to satisfy your curiosity again in the future. 

When it comes to true crime and curiosity, some people have an itch in their brain to learn what kind of people committed the crimes or were the victims of them. What happened that things ended up this way?

Yet, in a way, this could be brought back to the self-preservation instinct we talked about before. When you satisfy your curiosity about it, you also get a chance to rethink all your ties in life, whether they’re dangerous or not. 

Well, wanting to be aware of red flags, but justifying it with curiosity isn’t such a bad thing. Actually, any other reason you can list why people are so interested in true crime isn’t so bad, as long as it isn’t for the sake of copying what you see. Copycat crimes are a whole danger within themselves, but maybe that’s a topic for another day. Today let’s just stay with the one about red flags in people. 

What would you say is a trait in a person that hypothetically could suggest their bad intentions? Share with us in the comments!

Someone once called me a serial killer for eating string cheese without peeling it. I pointed out that a serial killer would more likely to be into peeling foods than not.

Those who know me better: " She also likes to collect knives and is fascinated with the human body.".
