Listen To What This Guy Says In His Sleep And Just Try Not To Laugh

Adam Rosenberg has been told a few times in his life that he talks in his sleep. But he didn’t have great proof until he downloaded and started using a sleep-tracking app on his phone. (Whenever the sound in the room reached a certain level, the app started to record.)

Rosenberg could make out that he was saying something during his slumber, but not what.

“It was distorted. I needed to find out more,” the 28-year-old independent filmmaker told The Huffington Post.

So he hooked up a better quality microphone. And what he played back sounded... confusing:

“Shhh. Shut up. Shut your fat butt. You fuck buck,” was one line he recorded, which he included in the video he made out of the recordings earlier this year (watch it in full at the top of the article). 

The images of Rosenberg sleeping in his bed and the microphone in the video are a reenactment, but the audio ― besides the voiceovers ― are all real recordings of Rosenberg’s sleep. 

“Just add look dust! Da Look as. Cause, cause you act like a booger cause, you fuzzy. Cause it fancy,” is another line.

Other mutterings might be considered more... poetic?

”Strength. Warrior strength.”

And other mumblings were just gibberish (as far as he knows), Rosenberg said.

“Keedle? Keedle-leedle-leedle-loodle? Dooda-laddle?”

“It almost sounded like different languages sometimes,” Rosenberg said ― though he doesn’t speak any languages other than English (and three years of high school Spanish).

“And it wasn’t just my normal speaking voice,” he said. “It was really strange and funny and weird.”

Sleep experts say it’s actually totally normal for people who talk in their sleep to say things that make no sense at all ― though some people who do it can relate their mumblings to past events or experiences. 

Rosenberg said he doesn’t remember connecting any of the recordings he listened to to specific dreams or experiences.

Somniloquy (the formal word for chronic “sleep talking”) is technically considered a sleep disorder when it happens in adults, though it tends to not be physically harmful ― other than potentially being embarrassing, annoying a bed fellow or disruptive to others sleeping nearby. 

Though it depends on what you find annoying...

“Pip pup pup pup pup pup pup pup pup pup pup pup pup pup pup pup pup pup psssssssss,” Rosenberg says about a minute and a half into the video. 

Because most people aren’t aware whether they do it or not, it’s difficult to put a number to exactly how common sleep talking is. 

Some experts suspect the behavior may run in families. Others suspect stress, depression, sleep deprivation, daytime drowsiness, alcohol, fever or other sleep sleep disorders could all be potential causes of sleep talking. And if the episodes do become severe or problematic, the National Sleep Foundation recommends individuals talk to their physician or health care provider to determine if one of these underlying problems is the cause and needs to be dealt with. 

“So what does it all mean? Is there a significance to all the things I say in my sleep?” Rosenberg asks at the end of the video. “Or is it just meaningless rambling ― the insignificant reflex of an unconscious mind?”

You’ll have to watch the video to find out the answer.
