For months, Grady was convinced a stranger was hiding in his house. Then he saw a pair of eyes.

Welcome.

Settle in for a spooky read courtesy of one of the weirdest Twitter threads in existence.

No, seriously, it’s basically our worst nightmare.

In a lengthy Twitter thread, Grady Hendrix shared his alleged childhood experience involving a man… living in his ceiling.

Unsurprisingly, the wild thread is going viral – and it’s not hard to see why.

Psychic Debbie Malone shares how to know if there are spirits around. Post continues after video.

Here’s how it all went down:

The story begins when Hendrix, then nine years old in 1981, decided to sneak downstairs for a late-night snack of leftover sweet and sour pork.

Sounds like a good plan, right?

Well. After making his way downstairs in the pitch-black towards the kitchen, Hendrix found something terrifying.

“I finally stepped into the totally dark den and let down my guard. All of a sudden I heard a fork clink on the counter. I froze,” Hendrix wrote.

“The microwave clock light showed the outline of a man sitting on our kitchen counter,” he continued.

“He couldn’t see me, but I saw him: a skinny guy, eating our leftovers, and drinking our milk from the carton.”

Um, NOPE.

After finding the man in the kitchen, Hendrix silently crept upstairs to wake up his mum and dad. But by the time his parents made their way downstairs, the kitchen was empty.

“Everyone said I read too many horror comics so they blew off what I said,” Hendrix said. “But there was no way I was pouring milk on my cereal.”

In the weeks that followed, Hendrix tracked the position of everything in the kitchen.

“One day the paper napkin holder was on the wrong side of the counter. Another day, a mug was in the sink that was NOT there the night before,” he wrote.

But… it gets worse.

“In August, I was in my room reading when I looked up,” Hendrix wrote.

“There’s an A/C vent over my bed. Behind the vent, a pair of eyes were watching me.”

Although Hendrix’s parents searched the attic and the crawl space under the house, nothing was found.

…Until a few weeks later.

“The last week of August our house started to smell. One night, rice fell out of the vent above my bed. Maggots. The A/C people said something had probably crawled into our vents and died,” Hendrix explained.

“Turns out what had crawled into our vents and died was the guy. We lived in an old house with lots of space between the walls and big ducts. He’d been living in them since May. At least,” he added.

“He’d put a foam pad beside my bedroom vent so he’d be comfortable while he watched me. The police said he’d made lots of ‘drawings’ but when I asked they pretended they hadn’t said anything.”

In the end, the man was never identified and he was buried as a John Doe.

“To this day I can’t look inside the vents in houses,” Hendrix said.

Since sharing the thread, it’s safe to say Hendrix’s story has sufficiently creeped out a lot of people.

But as some Twitter users have pointed out, Hendrix is a writer specialising in horror meaning it’s possible that the incident… didn’t exactly happen.

Yes, it all sounds a bit far-fetched to us too but whether it’s a true story or merely a work of fiction, it’s ridiculously creepy nonetheless. ¯\_(ツ)_/¯
