Top 10 Most Chilling Episodes of The UnXplained Ranked by Mystery Score

The UnXplained, hosted by the legendary William Shatner, has tackled everything from ancient ruins and psychic powers to haunted artifacts and places where people vanish without a trace. But some episodes stand out — not just for what they reveal, but for what they leave unanswered.

Here are the 10 most chilling episodes of The UnXplained, ranked by how deeply they mess with your sense of reality.

10. 🧠 “Mind Over Matter” – Season 1, Episode 7

Mystery Score: 7/10

Can the human mind bend reality?

This episode explores people with superhuman pain tolerance, psychic abilities, and unexplained control over body functions. One man sets himself on fire… and doesn’t flinch. Another stops his own heartbeat.

Science shrugs. The mind remains uncharted.

9. ⛏️ “Mysterious Structures” – Season 2, Episode 4

Mystery Score: 7.5/10

From Puma Punku’s laser-cut stone blocks to the mind-boggling perfection of the Pyramids, this episode dives into architecture that shouldn’t exist.

Ancient construction, impossible precision, no tools to explain it.

Were they helped by something… or someone else?

8. 🕯️ “Dark Prophecies” – Season 2, Episode 6

Mystery Score: 8/10

What if ancient texts, dreams, or visions predicted the future?

From Nostradamus to the eerie predictions of the Hopi tribe, this episode examines prophecies that appear to match modern disasters, wars, and events.

Coincidence… or proof that time isn’t what we think it is?

7. ⚰️ “Cursed Objects” – Season 3, Episode 5

Mystery Score: 8.2/10

The cursed doll. The haunted mirror. The “dybbuk box.”

This episode takes a terrifying turn as experts discuss items that bring death, misfortune, and madness to those who own them.

These aren’t legends — they’re linked to real deaths and police reports.

After watching, you’ll think twice before buying that antique on eBay.

6. 🌫️ “The Oak Island Curse” – Season 4, Episode 3

Mystery Score: 8.5/10

Could a hidden treasure be protected by a deadly curse?

This crossover episode connects to The Curse of Oak Island, where centuries of failed excavations and unexplained deaths have turned one island into a burial ground for fortune hunters.

No treasure. No answers. Just more mystery.

5. 🔍 “The Greatest Mysteries of the Past” – Season 1, Episode 1

Mystery Score: 8.6/10

The pilot that set the tone — exploring disappearances, ancient relics, and civilizations lost to time.

It’s the perfect gateway drug into the series, covering unsolved puzzles that archaeology still can’t explain, and asking the one question that makes this show so addictive:

What if history is wrong?

4. 💀 “Evil Places” – Season 1, Episode 4

Mystery Score: 9/10

From the Suicide Forest in Japan to the Hoia Baciu Forest in Romania, this episode explores places where death lingers, compasses spin, and people report visions, dread, and even possession.

You don’t need ghosts to make this terrifying — the geography alone is enough.

3. 🧬 “Superhuman Feats” – Season 2, Episode 7

Mystery Score: 9.2/10

Is there a hidden genetic code behind miracles?

This jaw-dropping episode investigates people who survive terminal illnesses, perform impossible feats of strength, or live without food for years.

Doctors don’t understand it. Shatner doesn’t claim to.

But you’ll leave wondering if evolution has secrets we’ve only just begun to unlock.

2. 🛸 “Alien Encounters” – Season 3, Episode 1

Mystery Score: 9.5/10

Yes, The UnXplained goes there — and it does it better than most.

From ancient depictions of flying saucers to government whistleblowers and modern abduction claims, this episode walks the line between the Ancient Astronaut theory and modern UAPs.

And with the Pentagon now confirming UAP sightings, this one feels less like fiction and more like foreshadowing.

1. 📍 “Mysteries of the Brain” – Season 3, Episode 10

Mystery Score: 10/10

More terrifying than ghosts. More real than aliens.

This episode dives into the one thing we all have — but barely understand.

People wake up speaking foreign languages. Others suddenly develop musical genius after brain trauma. Cases of split personalities where each “self” has different physical conditions.

The brain is stranger than anything in space — and The UnXplained makes that terrifyingly clear.

👁️ Final Thoughts: The Truth May Be Stranger Than the Show

The UnXplained doesn’t give you answers.

It gives you reasons to question everything you thought you knew.

From ancient riddles to biological impossibilities, William Shatner leads us through the smoke — but he never tells you what’s behind the curtain.

Because maybe that’s the biggest mystery of all.
