You know that little voice in your head that's probably reading this article to you right now?
Well, the internet have been left absolutely reeling after finding out that not everyone has one, leaving many to debate the presence of the 'little voice' altogether.
And, let's just say it's sparked quite the buzz across social media.
One woman, Kelly Marie Wheeler, took to Facebook to share the bombshell revelation, writing: "My husband has just informed me he doesn't have a voice in his head I always knew he didn't dream or remember his dreams, but when I mentioned about the little voice in his head he looked at me like I'm crazy.
"Does anyone else not have a little voice in their head?"
It's clear that the people of the internet couldn't wait to share their responses to the woman's call-out after her post went viral, clocking up more than 2.8k comments in less than 24 hours since it was first posted.
Many were clearly just as shocked as Kelly was with one Facebook user writing: "This has blown my mind I have to be honest!!"
"Are [sic] there people who don't have a monologue and conversations in their head?? How?" wondered a second.
Another echoed: "I thought everyone had a voice... can't imagine peace."
Me neither to be honest.
A fourth admitted: "Yep my husband is the same, doesn't have an inner monologue or see anything other than his eyelids when he closes his eyes. I find it very odd as mine never shuts up and my imagination runs rife."
Another echoed: "My partner says he doesn't have a conversation with himself in his head ever. Because I have a serious matter with myself I can't imagine how it would work if I didn't!! Men are from Mars."
"Most men don't," claimed a sixth. "I watched a documentary about it."
Many were baffled at how such people read without the help of their 'little voice', with one Facebook user wondering: "How does one read without a little voice in their head?"
"If you don't have a voice in your head, do you read this post out loud?" asked a second. "I read everything in my head with my inner voice."
A third quipped: "I talk to myself all the time and reply to my own questions! Some weird people about..."
"I have a voice," chimed in a fourth, "drives me mad some days."
A fifth added: "Oh I have a whole fantasy world in my head! Keeps me sane lol!"
But what actually is the 'little voice' many of us have in our heads?
Well, it's called an inner monologue and an expert has revealed that it is true that not everyone has one.
"It is a relatively new finding though; the belief historically had been that everyone had an internal monologue."
Other Facebook users echoed this point, with one stating: "Just like we can't imagine what it's like to not have a voice in our heads, they can't imagine what it's like to have one.
"I only found out recently that not everyone has it, and other people even think in pictures."
A second explained: "Some people can't imagine things in their mind either. So if you asked them to picture a rainbow they couldn't. But they would be able to describe one no problem.
"Same for internal monologue. Some people hear their own voice, some people can hear different voices."
A third commented: "Some people don't have an inner voice, some people's thoughts are in pictures, colours and shapes."
"I don't have a voice in mine," revealed a final Facebook user. "I also can't visualise things."
