Your brain would rather be wrong than dead. 💀 That’s one reason we see faces where there aren’t any. Mistake a rock for a lion? Nothing happens. Mistake a lion for a rock? You’re lunch. 🦁 #SpookyScience #Pareidolia

We found a dog in a 1989 horror game. Me: “I don’t want to swing the axe at the dog!” 😭 Swings axe. Dog: eats my arm. Fair. Meanwhile Eon thinks we’ve finally found Tasmania’s missing thylacine. 😂 #RetroGaming #LastHalfOfDarkness

Your brain still thinks being alone in the dark could get you killed. 👀 So what does an ancient campfire have in common with a Twitch chat? More than you’d think. 🔥👻 #SpookyScience #FearOfTheDark

My mod hit me with a scream alert at EXACTLY the wrong moment in Phasmophobia. 💀 I panicked. I smoked my smudge too early. I unleashed obscenities. Thus was born: PREMATURE SMUDGELATION. 😂🔥 My mods are a menace. #Phasmophobia #HorrorGames

My Tesla told me to STOP for someone who wasn’t there. 👻 Beside a grave, Tesla Vision suddenly detected a figure directly in front of my car — and warned me not to hit them. Then I checked the camera. There’s nothing there. #Tesla #SpookyScience #WeirdTech

I BROUGHT MY DEAD TEAMMATE BACK. 💀 It took me ages to pull the right tarot card in Demonologist. Three seconds later, she pulled ONE card and hit the 1% chance of immediately dying again. I CAN’T SAVE THESE PEOPLE. 😂 #Demonologist #HorrorGames

I tried to MAKE my Tesla see a ghost.Angel statues right next to the car — nothing. Empty field, one Celtic cross — it saw a person walking. No one there.Same time of day. No idea what triggered it yet. Full test on YouTube 👇 #SpookyScience #Tesla #Paranormal #ScienceOfFear #GhostHunting

I went into the room completely defenceless. Found the clown ghost. Got the photo. Tried to run. The bastard had left a BALLOON in my escape route. 🎈🤡 I hit it, injured myself and suddenly couldn’t run. Somehow, I survived. 😂 #GhostExorcismInc #HorrorGames

The worst part of deep water isn’t always what might be hiding beneath you. Sometimes it’s simply how much nothing there is. 🌊 Why can vastness feel beautiful and terrifying? #Thalassophobia #SpookyScience #Fear

Dr Meredith Castles @meredithcastles.bsky.social · 28/08/2026

The Mortuary Assistant made me afraid of EVERYTHING. 💀 Corpses moving. Shadow figures. Demonic voices. And me eventually arguing with the supernatural. Apparently this is what I look like terrified. 😂👻 #TheMortuaryAssistant #HorrorGames

Dr Meredith Castles @meredithcastles.bsky.social · 27/08/2026

There’s something terrifying about endless. Space. The open sky. The deep ocean. Why can something so beautiful also make us feel so small — and so uneasy? 🌌🌊 Subscribe to @MeredithCastles on YouTube where we get curious about what makes us afraid #SpookyScience #Fear #Psychology

I walked every headstone and read every name. Next weekend, I sit down with a Ouija board and find out what actually happens. For science. 🕯️👻 #ouijaboard #scienceoffear

That "frozen" feeling when you look into deep water isn't automatically a phobia. Your brain just can't predict what's underneath — so it freaks out. 🧠🌊 Fear vs. phobia, explained. Full video on my YouTube channel. #thalassophobia #scienceoffear

A tornado was heading straight for me and I hid in exactly the wrong place. By pure luck, it skipped the house. 🌪️ "I should have moved" — yes, I did. Funnel Runners panic, straight from the stream. 🎮 #funnelrunners #horrorgaming

Finished a Ouija board session and now I can't stop checking the hallway. That heavy "someone's watching" feeling is real — but it's all in your brain. 👀🧠 The science of fear, explained. Full video on the channel. #ouijaboard #scienceoffear

Your brain isn't afraid of the doll. It's afraid of the glitch. 🧠👁️The uncanny valley is why dolls creep you out — the full science is in my latest Short.👇 youtu.be/Rhua3kLacA8

Your brain is not your friend at 3AM. New Short is up: why the dark scares us even when we know the hallway is empty. It's not ghosts — it's evolution. Your ancestors survived because they saw "something" in the shadows. Now you can't walk to the bathroom without a tiny existential crisis. YouTube👇

There's a scientific reason dolls make your skin crawl — and it's not the doll. It's the valley. Ventriloquist dummies. Clowns. Annabelle. Chucky. Why the uncanny valley is real, and why dolls sit at the bottom of it. Link in bio. #scienceoffear #uncannyvalley #pediophobia #psychology #creepydolls

3am. You wake up. The hallway is dark — and for a second, something is standing there. 🕯️ It's your brain doing what it evolved to do. Why are we afraid of the dark? Enjoy the Science of Fear series — link in bio. #scienceoffear #fearofthedark #psychology #nyctophobia #pareidolia

Dr Meredith Castles @meredithcastles.bsky.social · 11/08/2026

It's not waves. It's not creatures. It's your brain treating a dark empty space like a threat because it can't predict what's down there. The investigation continues. 🌊 #ScienceOfFear #Thalassophobia #DeepWater #BrainScience #ScienceCommunicator

The house is gone. The ruins are haunted. Bellevue was a Tasmanian mansion where three people were poisoned in 1831. The house was demolished. But the ruins — the last thing left on the estate — are still standing. And they're haunted. #Bellevue #DarkHistory #Tasmania #Haunted #HistoricalMystery

How many bodies are still under this park? 🪦 The headstones at St David's Park in Hobart were moved into a wall when the cemetery became a public park. But the bodies? They may still be under your feet. #DarkHistory #Tasmania #Hobart #HistoricalMystery #CreepyHistory

The most powerful ghost hunting tool isn't a spirit box — it's your phone. 📱👻 I used a 1932 newspaper article + Google Maps to find the exact location of a Tasmanian murder scene from 1831. The house is gone. The land remembers. #GhostHunting #GoogleMaps #DarkHistory #Tasmania #TrueCrime

I found John Bell's gravestone. But his body? That's somewhere else. When the headstones at Cornelian Bay were moved, the burial records lost all meaning. The stones are here. The people aren't necessarily underneath them. #Bellevue #TasmanianHistory #HistoricalMystery #DarkHistory #GraveMystery

While filming a video about Tesla’s famous “ghost detection” phenomenon, my mum stepped out of the car. The Tesla then appeared to detect TWO or THREE versions of her. 😳 A fascinating example of how computer vision systems can sometimes interpret the world in unexpected ways.

After testing the famous Tesla Ghost Theory, the answer appears to be no. But what we found was arguably more interesting: AI making the same kind of pattern-recognition mistakes humans make. The haunted bin bag remains unresolved. 👻🗑️ #TeslaGhost #Technology #AI #Science #Curiosity
