People Share The Most Terrifying Theories They've Ever Heard

Humanity has come up with some pretty interesting theories over the years.

Some are definitely more interesting than others.

Some of them are just downright terrifying.


Redditor Comprehensive-Note31 asked:

"What is the scariest theory known to man?"

Dual Consciousness Theory

"The dual consciousness theory disturbed me when I read about it."

"Basically (in my limited, layman understanding), a corpus callosotomy is a procedure that is sometimes used to treat conditions like epilepsy, where the connection between the two halves of the brain is severed."

"People can survive this and continue to live semi normally, but usually with some cognitive impairments. Both halves of the brain continue to be 'alive', but there is little to no communication between the two sides."

"People who undergo the procedure can also exhibit some strange phenomena like alien hand syndrome, where the patient feels like some of their limbs will move on their own accord. They can also have difficulty controlling their non-dominant hand, trouble speaking, and issues with certain parts of their vision."

"The dual consciousness theory posits that both halves of the brain retain a consciousness after this procedure. Essentially, you become two people sharing the same body, completely unaware of each other."

"One variation of the theory is that one half of the brain is dominant, controlling most bodily functions, while the other half is basically cut off from most external stimuli, unable to communicate with the outside world, for their rest of their life."

"Obviously this is only a theory and may not be correct. Also, even with the concerns around the operation I can totally understand parents choosing this for their kids - epilepsy can be a debilitating disease and this could be the only option."

"My sister had epilepsy and thankfully she got over it with medication, but it is brutal. Not everyone who has this operation has the side effects that I described, many of them lead normal lives."

"I'm not disturbed by people who have had this operation, just by the implications the theory could have for consciousness in general."

​The Great Filter

"The great filter. The idea that we see no other civilizations out in space because they hit some wall that made them go extinct."

"Whatever it may be, it could be the reason we see no intelligent life out there, the question is, are we past the filter, or is the worst still to come?"

-_Filter

"Good news, then"

"The Great Filter doesn't take into account that the Universe has only been liveable for an EXTREMELY short amount of time, and, in all likelihood, we are one of, if not the very, first advanced civilizations."

"Basically, the Great Filter doesn't say it's impossible for civilizations to get to the Expansionist and Grabby stages, just hard."

"And because it's just hard, that means that if there were advanced civilizations before our own, we would see the Grabby results of them."

"But we don't, which is not a confirmation of the Great Filter, but more an indication that we are very, very, very early in the timeline of this Universe's 'liveable' stage, & for expanding & becoming Grabby ourselves."

"So the Great Filter is more a cautionary hypothesis than it is a death sentence law of nature."

-emillang1000

Cold, Cold Death

"Cold Death of the universe. That the speed at which the universe is expanding is to the point where gravity will never pull it back."

"Matter will spread out and cool down and decay until everything, everywhere, just stops. forever."

-fdsdfg

We'd Never Know

​"The fact that it would take 8 minutes for earth to know that the sun exploded and it could have exploded 7 minutes ago"

-My-name-is-jef56

Proton Decay

"​The theory of proton decay, where every single bit of baryonic matter will eventually just spontaneously dissolve into radiation and fundamental particles, guaranteeing that there will be no survivors at the end of the universe is... yeah terrible"

-KentoKeiHayama

"Genuinely asking here; isn't the impending (but incomprehensibly far in the future) heat death of the universe a fairly widely-shared, well-grounded theory at this point? I'm not sure if the two are actually interchangeable so maybe this is a moot point. I don't know sh*t about sh*t so please feel free to ignore me."

-JamesSFordESQ

"There would still be matter with heat death - just cold and no interaction. The idea though is that, given enough time, it may be that protons decay too. If that is the case, then not only would the heat death occur, there would be no matter, either. From bleak to bleaker, really."

-WolfySpice

Uncanny Valley

"The idea that the Uncanny Valley is because of the ancient hominids we used to interact with during the Pleistocene. Sure, there were interbreeding events, but imagine if you had no idea what a Neanderthal or a Denisovan were and saw one for the first time."

"You and your family have been traveling far from home and seek refuge in a cave for the night. You get a fire going, everyone starts to relax."

"Then out of nowhere, this 'almost human' looking being walks up. You all panic and run. Reacting with fear was probably the easiest way to make it out of an encounter like that alive."

-Bromelia_and_Bismuth

Is It Just Me?

"Solipsism. Basically There's no way to prove that anyone other than yourself actually exists. You can dive deeper if you like its actually pretty interesting."

-CasualBiceps

"My dad's friend believes this. He's essentially seen enough therapists that he just finds it easier to 'go with the illusion'."

"He has a wife. He loves her. He 100% believes she's not real."

"She's aware of this, and for some reason takes him as he is. He's a really nice guy."

"He seems incredibly content. Like if this is what the matrix is giving him, he may as well find joy in it."

-A_Is_For_Azathoth

What Is Consciousness?

​"That our consciousness doesn't actually direct our actions, but just makes up stories to explain our actions to itself. Consciousness might not even be useful to our evolution, it could just be a weird phenomena that came about as our brains became more complex and developed more self-monitoring systems."

-anemonegemini

False Vacuum Decay

False vacuum decay

"In quantum field theory, a false vacuum is a hypothetical vacuum that is stable, but not in the most stable state possible (it is metastable). It may last for a very long time in that state, but could eventually decay to the more stable state, an event known as false vacuum decay."

"The most common suggestion of how such a decay might happen in our universe is called bubble nucleation – if a small region of the universe by chance reached a more stable vacuum, this 'bubble' (also called 'bounce')would spread."

-pradeep23

​We Literally Can't Know

"​What if our understandings of physics and science, what we base out whole lives around, is just wrong. A man born without eyes cannot see, what if we are missing a huge chunk of reality, simply due to an inability to detect it?"

-LucarioKing0

"This seems incredibly likely to me. Our senses evolved for survival, not necessarily for accurate perception of reality."

-fwonkas

Not all theories are scary, but some of these ones are getting into existential dread territory.

Remember, though, they're just theories—not facts.

People Who Actually Died And Were Revived Share Their Experiences

"Reddit user AlaskaStiletto asked: 'Redditors who have 'died' and come back to life, what did you see?'"

Experiencing death is a fascinating and frightening idea.

Who doesn't want to know what is waiting for us on the other side?

But so many of us want to know and then come back and live a little longer.

It would be so great to be sure there is something else.

But the whole dying part is not that great, so we'll have to rely on other people's accounts.

Redditor AlaskaStiletto wanted to hear from everyone who has returned to life, so they asked:

"Redditors who have 'died' and come back to life, what did you see?"

Sensations

Happy Good Vibes GIF by Major League SoccerGiphy

"My dad's heart stopped when he had a heart attack and he had to be brought back to life. He kept the paper copy of the heart monitor which shows he flatlined. He said he felt an overwhelming sensation of peace, like nothing he had felt before."

PeachesnPain

Recovery

"I had surgical complications in 2010 that caused a great deal of blood loss. As a result, I had extremely low blood pressure and could barely stay awake. I remember feeling like I was surrounded by loved ones who had passed. They were in a circle around me and I knew they were there to guide me onwards. I told them I was not ready to go because my kids needed me and I came back."

"My nurse later said she was afraid she’d find me dead every time she came into the room."

"It took months, and blood transfusions, but I recovered."

good_golly99

Take Me Back

"Overwhelming peace and happiness. A bright airy and floating feeling. I live a very stressful life. Imagine finding out the person you have had a crush on reveals they have the same feelings for you and then you win the lotto later that day - that was the feeling I had."

"I never feared death afterward and am relieved when I hear of people dying after suffering from an illness."

Free

The Light Minnie GIF by (G)I-DLEGiphy

"I had a heart surgery with near-death experience, for me at least (well the possibility that those effects are caused by morphine is also there) I just saw black and nothing else but it was warm and I had such inner peace, its weird as I sometimes still think about it and wish this feeling of being so light and free again."

TooReDTooHigh

This is why I hate surgery.

You just never know.

Shocked

Giphy

"More of a near-death experience. I was electrocuted. I felt like I was in a deep hole looking straight up in the sky. My life flashed before me. Felt sad for my family, but I had a deep sense of peace."

Admirable_Buyer6528

The SOB

"Nursing in the ICU, we’ve had people try to die on us many times during the years, some successfully. One guy stood out to me. His heart stopped. We called a code, are working on him, and suddenly he comes to. We hadn’t vented him yet, so he was able to talk, and he started screaming, 'Don’t let them take me, don’t let them take me, they are coming,' he was scared and yelling."

"Then he yelled a little more, as we tried to calm him down, he screamed, 'No, No,' and gestured towards the end of the bed, and died again. We didn’t get him back. It was seriously creepy. We called his son to tell him the news, and the son said basically, 'Good, he was an SOB.'”

Colors

"My sister died and said it was extremely peaceful. She said it was very loud like a train station and lots of talking and she was stuck in this area that was like a curtain with lots of beautiful colors (colors that you don’t see in real life according to her) a man told her 'He was sorry, but she had to go back as it wasn’t her time.'"

Hannah_LL7

"I had a really similar experience except I was in an endless garden with flowers that were colors I had never seen before. It was quiet and peaceful and a woman in a dress looked at me, shook her head, and just said 'Not yet.' As I was coming back, it was extremely loud, like everyone in the world was trying to talk all at once. It was all very disorienting but it changed my perspective on life!"

The Fog

"I was in a gray fog with a girl who looked a lot like a young version of my grandmother (who was still alive) but dressed like a pioneer in the 1800s she didn't say anything but kept pulling me towards an opening in the wall. I kept refusing to go because I was so tired."

"I finally got tired of her nagging and went and that's when I came to. I had bled out during a c-section and my heart could not beat without blood. They had to deliver the baby and sew up the bleeders. refill me with blood before they could restart my heart so, like, at least 12 minutes gone."

Fluffy-Hotel-5184

Through the Walls

"My spouse was dead for a couple of minutes one miserable night. She maintains that she saw nothing, but only heard people talking about her like through a wall. The only thing she remembers for absolute certain was begging an ER nurse that she didn't want to die."

"She's quite alive and well today."

Hot-Refrigerator6583

Well let's all be happy to be alive.

It seems to be all we have.

Man's waist line

Trying to lose weight is a struggle understood by many people regardless of size.

The goal of reaching a healthy weight may seem unattainable, but with diet and exercise, it can pay off through persistence and discipline.

Seeing the pounds gradually drop off can also be a great motivator and incentivize people to stay the course.

Those who've achieved their respective weight goals shared their experiences when Redditor apprenti8455 asked:

"People who lost a lot of weight, what surprises you the most now?"

Redditors didn't see these coming.

Shiver Me Timbers

"I’m always cold now!"

– Telrom_1

"I had a coworker lose over 130 pounds five or six years ago. I’ve never seen him without a jacket on since."

– r7ndom

"140 lbs lost here starting just before COVID, I feel like that little old lady that's always cold, damn this top comment was on point lmao."

– mr_remy

Drawing Concern

"I lost 100 pounds over a year and a half but since I’m old(70’s) it seems few people comment on it because (I think) they think I’m wasting away from some terminal illness."

– dee-fondy

"Congrats on the weight loss! It’s honestly a real accomplishment 🙂"

"Working in oncology, I can never comment on someone’s weight loss unless I specifically know it was on purpose, regardless of their age. I think it kind of ruffles feathers at times, but like I don’t want to congratulate someone for having cancer or something. It’s a weird place to be in."

– LizardofDeath

Unleashing Insults

"I remember when I lost the first big chunk of weight (around 50 lbs) it was like it gave some people license to talk sh*t about the 'old' me. Old coworkers, friends, made a lot of not just negative, but harsh comments about what I used to look like. One person I met after the big loss saw a picture of me prior and said, 'Wow, we wouldn’t even be friends!'”

"It wasn’t extremely common, but I was a little alarmed by some of the attention. My weight has been up and down since then, but every time I gain a little it gets me a little down thinking about those things people said."

– alanamablamaspama

Not Everything Goes After Losing Weight

"The loose skin is a bit unexpected."

– KeltarCentauri

"I haven’t experienced it myself, but surgery to remove skin takes a long time to recover. Longer than bariatric surgery and usually isn’t covered by insurance unless you have both."

– KatMagic1977

"It definitely does take a long time to recover. My Dad dropped a little over 200 pounds a few years back and decided to go through with skin removal surgery to deal with the excess. His procedure was extensive, as in he had skin taken from just about every part of his body excluding his head, and he went through hell for weeks in recovery, and he was bedridden for a lot of it."

– Jaew96

These Redditors shared their pleasantly surprising experiences.

Shopping

"I can buy clothes in any store I want."

– WaySavvyD

"When I lost weight I was dying to go find cute, smaller clothes and I really struggled. As someone who had always been restricted to one or two stores that catered to plus-sized clothing, a full mall of shops with items in my size was daunting. Too many options and not enough knowledge of brands that were good vs cheap. I usually went home pretty frustrated."

– ganache98012

No More Symptoms

"Lost about 80 pounds in the past year and a half, biggest thing that I’ve noticed that I haven’t seen mentioned on here yet is my acid reflux and heartburn are basically gone. I used to be popping tums every couple hours and now they just sit in the medicine cabinet collecting dust."

– colleennicole93

Expanding Capabilities

"I'm all for not judging people by their appearance and I recognise that there are unhealthy, unachievable beauty standards, but one thing that is undeniable is that I can just do stuff now. Just stamina and flexibility alone are worth it, appearance is tertiary at best."

– Ramblonius

People Change Their Tune

"How much nicer people are to you."

"My feet weren't 'wide' they were 'fat.'"

– LiZZygsu

"Have to agree. Lost 220 lbs, people make eye contact and hold open doors and stuff"

"And on the foot thing, I also lost a full shoe size numerically and also wear regular width now 😅"

– awholedamngarden

It's gonna take some getting used to.

Bones Everywhere

"Having bones. Collarbones, wrist bones, knee bones, hip bones, ribs. I have so many bones sticking out everywhere and it’s weird as hell."

– Princess-Pancake-97

"I noticed the shadow of my ribs the other day and it threw me, there’s a whole skeleton in here."

– bekastrange

Knee Pillow

"Right?! And they’re so … pointy! Now I get why people sleep with pillows between their legs - the knee bones laying on top of each other (side sleeper here) is weird and jarring."

– snic2030

"I lost only 40 pounds within the last year or so. I’m struggling to relate to most of these comments as I feel like I just 'slimmed down' rather than dropped a ton. But wow, the pillow between the knees at night. YES! I can relate to this. I think a lot of my weight was in my thighs. I never needed to do this up until recently."

– Strongbad23

More Mobility

"I’ve lost 100 lbs since 2020. It’s a collection of little things that surprise me. For at least 10 years I couldn’t put on socks, or tie my shoes. I couldn’t bend over and pick something up. I couldn’t climb a ladder to fix something. Simple things like that I can do now that fascinate me."

"Edit: Some additional little things are sitting in a chair with arms, sitting in a booth in a restaurant, being able to shop in a normal store AND not needing to buy the biggest size there, being able to easily wipe my butt, and looking down and being able to see my penis."

– dma1965

People making significant changes, whether for mental or physical health, can surely find a newfound perspective on life.

But they can also discover different issues they never saw coming.

That being said, overcoming any challenge in life is laudable, especially if it leads to gaining confidence and ditching insecurities.

In 2017, I returned to my office after my lunch break to hear my supervisors discussing Tom Petty. This seemed like a random topic to me until one of my supervisors told me Tom Petty had passed away. He was a huge fan of Petty and spent the next hour or so combing through the internet to get more information.

He came back into the room my other supervisor and I were working in and announced that Tom Petty wasn't dead after all. News outlets had jumped the gun to announce his death, but he was actually still alive.

The next day, I came in to find out that Tom Petty was dead; the news may have been premature, but true.

This is a classic example of the rumor being started on the internet. Sometimes, like with the news of Tom Petty's death, the rumor can run wild and appear everywhere. Other times, the rumor can be seen by just a few people and dismissed. However, a lot of times, these rumors turn out to be true.

Redditors know a lot of internet rumors that turned out to be true, and are eager to share.

It all started when Redditor strakerak asked:

"What started out as an internet rumor that ended up being infamously true?"

The King Of Pop

"Michael Jackson writing the music for Sonic 3."

"He actually did, but was never credited on the game because it would breach his contract with his record label."

– -WigglyLine-

"He did the same when he appeared on The Simpsons. He appeared under a pseudonym, and the Producers said it was an impersonator."

"Only years later they confirmed it really was Michael."

"His singing voice was actually done by an impersonator, though."

– given2fly_

The Truth Comes Out

"In 1998, US Men’s National Team captain John Harkes was shockingly cut from the team right before the World Cup. The coach claimed it was because Harkes wouldn’t fit into his new preferred formation, but rumors flew on the early internet that it was actually because he had slept with his teammate Eric Wynalda’s wife. The rumor was so well-known in soccer circles that Harkes expressly denied it in his autobiography the next year."

"Fast forward 12 years to 2010 and Wynalda admits it’s true. The coach then came out and admitted it was why he dropped Harkes, but that he’d planned to keep the secret as long as Wynalda did."

– guyfromsoccer

Video Evidence

"The Tim Burton Hansel and Gretel that aired once on halloween in the 80's."

"I heard for years that it was fake but I knew it was real because my dad recorded everything in the 80s and he recorded that. We let a good friend of ours borrow it and switch it over from VHS to DVD and soon after that it made its way on to the internet , and there it is now. I know it's our copy because the tracking in the beginning is screwed up. Still have the VHS."

– Frozenthickness

"There was a similar story with a Nickelodeon movie called Cry Baby Lane. It was supposed to be so scary that Nickelodeon got complaints and denied its existence for years. Someone uploaded a taped copy to youtube about a decade ago."

– PattiAllen

The Movie Business

"That North Korea hacked Sony Pictures because of The Interview movie."

"I worked in the movie business at the time and the account managers at Sony all basically needed to get new identities as all of their personal information got leaked online."

OldMastodon5363

"My partner worked on that movie and the production bought all the crew 1 year of an identity theft tracking service."

CMV_Viremia

Keep Away From The Ears Of Kids

"Some banned episodes or scenes of cartoons."

"For example, I remember there was a Dexter’s Lab cartoon where he clones evil versions of DeDe and himself and they swear like every other word (censored of course), and people debated whether it even existed cause they only aired it like once. Now it’s pretty accessible online."

– Spledidlife

Yes, It's True

"Echelon, a massive electronic espionage system by the US and allies to intercept all electronic messages, especially emails."

"In the mid-nineties it was a topic on conspiracy BBS boards. A lot of people in my bubble at the time (mainly uni students in Europe) were including fake threats to the US in the their email signatures as a way to "protest" and "fill the system with false alarms" (obviously useless)."

"Then, in 1999-2000 came out to be true and a lot of security service agencies from UK and other US allies started to admit they were part of the espionage network."

– latflickr

How The Mighty Fell

"John Edward’s love child."

– ACam574

"A reminder that he was cheating on his wife while she was hospitalized for cancer treatment."

– Fanclock314

Ugh...

"Carrie Fisher's heart attack. Some a**hole who was on the same flight was livetweeting the whole medical emergency and justified it by insisting she was just making sure the family was informed."

– everylastlight

It Actually Happened

"Every year around her birthday there was a rumor that Betty White died. When I heard she died, I scoffed, saying that dumb rumor is back.... then saw it on the news. I was in shock."

– Known-Committee8679

"The fact that Betty died literally right before she turned 100 is such a Betty White way to go out."

– Paganigsegg

Big Actor, Small Roles

"I distinctly remember some rumors about the reason why Bruce Willis was taking so many roles in sh*tty movies before it was announced he has dementia."

– KampferMann

"RedLetterMedia did a deep dive on his recent movie activity to try and work out why exactly he was taking part in basically scam-movies. They noticed he had an earpiece in one of the scenes and joked that the director was feeding him lines. I remember they even disclaimed over the rumours at the time, and possible made a follow-up vid when it was revealed to the public."

– CardinalCreepia

What To Do Next?

"That the writer of LOST were making it up as they went."

"Turned out to be absolutely true."

– homarjr

That last one was kind of obvious!
