Have you ever uttered the words "sleep tight" or "hit the hay" before going to bed? These phrases have existed for ages, but their meanings and origins are not always apparent. Some are directly related to sleeping, while others are metaphors for entirely different things. Take a look at 12 of these idioms. Do you use any of them?

1

Sleep tight

"Sleep tight" is a phrase most people know from the bedtime verse: "Sleep tight, don’t let the bedbugs bite". It’s often claimed to come from the old practice of tightly tying ropes on bed frames to keep mattresses firm and comfortable. This helped prevent sagging and made for a better night’s sleep.

In older English, "tight" simply meant "soundly" or "well", making "sleep tight" a wish for a good night’s sleep.

Hit the hay

"Hit the hay" dates back to the late 19th or early 20th century and is often linked to the practice of stuffing hay into sacks or mattresses for sleeping, which is also commonly cited as an explanation for the phrase "hit the sack."

Another theory suggests that farm workers sometimes slept directly in haystacks, making "hay" a stand-in for "bed." Because "hit the hay" appears in print slightly earlier than "hit the sack," some believe it may have come first.

To sleep like a baby

Anyone who has had a newborn knows how strange the phrase "sleep like a baby" sounds: babies wake up often and cry! Yet, the idiom means to sleep peacefully and deeply.

The idea is that when babies do sleep, they’re completely at ease, with no worries to disturb them. That peaceful, undisturbed state is what the phrase refers to, even if it doesn’t match the full reality.

Let sleeping dogs lie

"Let sleeping dogs lie" might sound odd at first, but its meaning becomes clear with a bit of explanation. It’s a warning to leave past issues alone, especially sensitive ones.

The phrase compares old disputes to sleeping dogs: if you wake them, they might react aggressively. Similarly, revisiting old problems can stir up trouble best left alone.

5

A catnap

A "catnap" is a short, light nap, usually under 30 minutes, during which you do not enter deep sleep. Studies suggest that even a 10-minute nap can be refreshing, sometimes nearly as effective as a longer one, though the ideal length varies by person.

The term comes from cats’ daytime sleep habits. Since wild cats had to stay alert for danger, they took quick, light naps. Today’s cats do the same, snoozing lightly throughout the day, just like a good catnap.

6

Wrong side of the bed

"Waking up on the wrong side of the bed" means starting the day in a bad mood. The phrase comes from an old Roman superstition.

Romans, including Augustus Caesar, believed getting up on the left, or sinister, side brought bad luck. As a result, the "wrong side" was more than just a bad mood starter; it was thought to be a bad omen.

7

Sleep like a log

To "sleep like a log" means to sleep deeply and without moving, like a heavy log lying still. It’s a common way to describe a peaceful, undisturbed night.

The origin of the phrase is unclear, but some link it to lumberjacks who slept soundly after hard work. Others connect it to the similarity between snoring and the sound of sawing.

8

Counting sheep

"Counting sheep" means imagining sheep jumping over a fence, one by one, to help you fall asleep. It’s a classic mental trick to quiet the mind.

The phrase likely comes from shepherds who counted their flocks at night to ensure none were missing, a repetitive and calming routine before bed.

9

Lose sleep over something or somebody

Image: Михаил Калегин

The idiom "to lose sleep over something" means to worry about something to the point that it becomes difficult to sleep, or to be so concerned that it disrupts one’s rest.

While the exact origin of the phrase is difficult to pinpoint, it likely evolved from the idea that intense worry and stress can interfere with the body's natural sleep cycle.

10

Do something in your sleep

Image: Nubelson Fernandes

To "do something in your sleep" means to do something very easily and effortlessly, usually because you have done it so many times that it's become second nature. It's a metaphorical way of saying that you are so proficient at a task that you don't even have to think about it, as if you could do it while unconscious.

11

Sleep with one eye open

Image: Jamie Street

"Sleep with one eye open" means staying alert or cautious, especially in risky situations. It suggests being ready for trouble, even while resting.

The phrase is often linked to animals such as dolphins and certain birds that can literally sleep with part of their brain awake to remain safe.

12

Sleep around the clock

To "sleep around the clock" means to sleep for many hours without waking. It often happens when you're exhausted or feeling unwell. It’s a way in which the body tries to recover energy.

"For what is a man?": Some of the wisest lyric lines ever written


Published on March 24, 2026

Paul Anka was terrified when he sat down to write the lyrics for a song that Frank Sinatra would be singing. Jokingly, he started with a dramatic, "And now, the end is near…" The rest is history. Who are the people who pen the words that others will spend decades repeating? How did they come up with words so precise and true that listeners would compare them with those of great philosophers? Here are 10 of people’s favorite lyrics of all time, decoded.

1

"For what is a man? What has he got?"

"For what is a man? What has he got? If not himself, then he has naught." The melody of "My Way" wasn't originally American. It began as a French song called Comme d'habitude, a number about a couple stuck in a stale marriage. Paul Anka heard it on the radio while in France and bought the rights on the spot, before he had any use for it.

That use arrived at a dinner in Miami, when Sinatra told him, almost in passing, that he was quitting the business. Anka flew home, sat down at a typewriter, and spent one night writing lyrics as if Sinatra himself were speaking them. Sinatra recorded it in two takes and later called it his "national anthem," and many agreed; Anka had written the exact words one wants to belt while closing an episode of their life.

"Life is what happens to you…"

In "Beautiful Boy (Darling Boy)," John Lennon wrote: "Life is what happens to you while you are busy making other plans." But the phrase originated with American writer and cartoonist Allen Saunders, who published it in a 1957 issue of Reader's Digest ("Life is what happens to us while we are making other plans").

The line outlived everything else about the song, repeated at graduations and eulogies for decades since. Lennon was murdered shortly after the album's release, which means the song now carries a weight of hindsight neither he nor his listeners could have intended at the time.

"How many roads must a man walk down…"

"How many roads must a man walk down before you call him a man?" A young Bob Dylan wrote "Blowin' in the Wind" in 1962. He later claimed he wrote the entire song in about ten minutes at the Gaslight Cafe in Greenwich Village, borrowing its melody from the old spiritual "No More Auction Block." He was twenty-one, barely a year into his New York career, and insisted at the time it wasn't a protest song at all.

The song never answers its questions, but keeps asking them. First published in the folk magazine Broadside in May 1962, it became the unofficial anthem of the civil rights and antiwar movements once Peter, Paul and Mary's cover shot to number two on the charts in 1963.

"And in the end, the love you take…"

"... is equal to the love you make." This is the last song the four Beatles ever recorded together, and Paul McCartney built it deliberately as a farewell. He gave Ringo Starr his only drum solo in the band's history, a fight McCartney had to win through what he called "gentle persuasion," since Starr detested solos on principle.

For the closing line, McCartney said he'd been thinking about Shakespeare, who often ended a scene with a rhyming couplet so the audience would know it was truly over. Even John Lennon, who generally disliked the Abbey Road medley and rarely praised his old partner's work by 1980, admitted the closing thought was "a very cosmic, philosophical line."

"They’re sharing a drink they call loneliness…"

"... but it’s better than drinking alone." "Piano Man", by Billy Joel, narrates a song in which the character is real. Joel wrote it about the six months he spent playing piano under the fake name "Bill Martin" at a Los Angeles lounge called The Executive Room. Even the waitress "practicing politics" was Elizabeth Weber, the woman who'd soon become his wife.

Joel wrote it while hiding out from a record label he was desperate to escape after his debut album flopped. It became a bittersweet anthem that many people love singing with others; it seems like, as the song suggests, singing sorrows together at the bar is better than feeling them at home.

"I've looked at love from both sides now…"

Image: Arthur D'Amario III

The whole song "Both Sides Now," by Joni Mitchell, is often quoted as a deeply philosophical observation of life. It concludes that some mysteries of life are as unknowable as the clouds, or love, despite accumulating experience.

When she wrote it, Mitchell had recently given up a daughter for adoption after being left by the child's father. She was twenty-three, mid-flight, after a passage in Saul Bellow's novel Henderson the Rain King described its narrator looking down at clouds from an airplane, something human eyes had only been able to do for a few decades. Judy Collins released it first in 1967 and won a Grammy for it; Mitchell's own version didn't appear until her 1969 album Clouds.

"I’d trade all of my tomorrows for one single yesterday"

Kris Kristofferson’s song, "Me and Bobby McGee", contains one of people’s favorite quotes from song lyrics. Its title came from producer Fred Foster, who suggested Kristofferson write a song about his colleague's secretary, Barbara "Bobbie" McKee.

Its most quoted idea about freedom and loss was inspired, Kristofferson later said, by the final scene of Fellini's La Strada, in which a man realizes too late what he threw away. Roger Miller released it first, but it was Janis Joplin's posthumous 1971 recording, finished mere days before her death, that turned it into a number one hit and an accidental epitaph.

"But time makes you bolder, even children get older…"

"... and I'm getting older too." Nicks says she wrote "Landslide" in about five minutes, sitting in a rented house in Aspen while her partner and musical collaborator, Lindsey Buckingham, was on tour rehearsing with the Everly Brothers. The song's real subject isn't romance, but the vertigo of watching time pass. She was twenty-seven, broke, working as a waitress and a cleaner, and their duo album had just been dropped by its label.

Looking at the snow on the Rockies, she found herself deciding whether to keep chasing music at all. Three months later, Mick Fleetwood heard Buckingham's guitar work on a demo and invited the pair into Fleetwood Mac, which changed their lives. The song has now aged into an anthem for anyone facing a hinge point in their own life.

"You can't always get what you want…"

"You can't always get what you want, but if you try sometime you'll find you get what you need." Mick Jagger sketched this one alone on an acoustic guitar, calling it "one of those bedroom songs." It closed 1969's Let It Bleed just as the decade's peace-and-love optimism was cracking.

The song is upbeat and simple, and unexpectedly insists on an idea of acceptance or surrender that has more to do with Stoic philosophy than with pop rock optimism. But the listeners liked it, and many quote it often.

"There is a crack in everything…"

"...that's how the light gets in." Leonard Cohen worked on "Anthem" for roughly a decade, discarding draft after draft, before it finally appeared on his 1992 album The Future. He wasn't a man given to explaining his own lyrics, having spent years training as an ordained Zen Buddhist monk and generally preferring silence to self-analysis.

But "Anthem" has the clearest statement of a philosophy he'd circled his entire career: that brokenness can give way to grace. It has since been invoked by human rights activists, quoted at protests, and performed at civic ceremonies.
