5 Scientific Facts About Your Dreams

ThinkStock

Throughout human history, dreams have been the subject of science and pseudoscience alike. In today’s crazy online world where you can’t always believe your eyes, we hope you’ll sleep better knowing that the following facts are the real deal.

1. Dream logic is neurologically logical

Your brain’s activity looks very different when you’re asleep, which sheds some light on the nature of dreams. For starters, your primary visual cortex is out of commission during sleep (because your eyes are closed), but your secondary visual cortex (which normally interprets outside visual stimuli) is still going at it, trying to make sense of the images the rest of your brain is conjuring up.

Your limbic system (hippocampus and fornix––the wormy tangle all up in the middle of your brain) is the primary control center for your emotions, and it becomes especially active during your dreams. This explains why dreams are so emotionally charged, and often deal with feelings of imminent danger. Meanwhile, the dorsolateral prefrontal cortex, which controls logic and rationality, is practically dormant, which explains why you can dream yourself marrying Hugh Griffith in an cosmonaut suit and be like, “Can we have the guests throw sand instead of Cracker Jacks, Hughie? Birds tend to choke on the prizes.”

2. You also dream during “non-REM” sleep

By now everyone knows that we categorize human sleep in five stages: some deep stages with boring number-names, and REM, famously responsible for dream time. Au contraire! More recent research indicates that dreaming also occurs during non-REM sleep (slyly abbreviated as NREM). REM sleep is the stage closest to waking, though, so you’re more likely to remember REM dreams than those in NREM.

Since each sleep stage represents different brain activity, different stages will result in different types of dreams. During REM sleep, for instance, people typically report interacting with two to three characters outside of themselves––usually people they know in waking life––while NREM may host more characters, more of whom are strangers. At the same time, the dreamer more often initiates socially aggressive interactions in REM sleep, while NREM hosts friendlier social initiations. Makes it hard not to read a “don’t you dare wake me up” subtext into those REM dreams... 

3. Pain Can Show Up in Dreams

While it’s never been proven that dreams themselves can produce pain, a few studies have suggested that real-world pain can incorporate into dreams. In one study, a lab-induced “pins and needles” sensation manifested as a problematic shoe-fitting in the subject’s dream, while more intense pain (like that experienced by healing burn victims in a 2002 study) can produce nightmares wherein the dreamer tries to escape the source of their pain, literally and metaphorically. In short, pain transcends the barrier between waking and dreaming life, and shows up in our dreams relatively untransformed. 

4. Dreams Help You Learn

You’ve heard the term “Let me sleep on it,” from Meat Loaf and others, and it’s a good idea, scientifically speaking. That’s because your brain can teach itself while you sleep, thanks to a process Harvard neuroscience professor Robert Stickgold calls off-line memory reprocessing.

In his series of experiments, Stickgold had subjects perform simple tasks like recognizing words or hitting a digital target, and compared their progress with their sleep patterns. The logic is this: Any time you make a memory, that new information has to transfer between several different parts of your brain in order to stick around for awhile, and those same patterns correspond with the patterns of brain activity during sleep. Sure enough, subjects who slept on their lessons showed greater improvement. In his Tetris experiment, Stickgold’s subjects even reported dreaming about Tetris as the learning period went on, indicating a connection between the need to improve, dreams, and post-dream improvement.

5. Dreams do Affect Your Mood

You probably already knew this: The tone of a dream can set the tone of the following morning, for better or worse. But there’s more to it than that. “Daytime mood and social interactions” have been found to correlate with dream details––although universal patterns across dreams are almost impossible to quantify reliably. Details as seemingly arbitrary as the number of characters the dreamer encounters may have more to do with the person’s actual sleep patterns than actual dream content (see bullet #2). But as in Stickgold’s memory experiments, dreaming about stuff that’s bothering you can help the brain process during sleep what you might not be thrilled to process during the day (see bullet #5). In short: Dream on, little dreamer. It’s good for ya.

11 Single Facts About Bridget Jones’s Diary
Miramax
Miramax

While it's not officially a holiday movie, so much of the action in Bridget Jones's Diary happens around the most wonderful time of the year that the rom-com has become essential wintertime viewing for many movie fans. Based on Helen Fielding’s novel of the same name, it tells the story of a very single, and hopelessly romantic, working professional named Bridget (Renée Zellweger) who is determined to improve her love life. Enter two strapping gentlemen (Colin Firth and Hugh Grant) to vie for her heart. Get to know more about the timeless dramedy that’s been delighting audiences since 2001. Just as it is.

1. THE SOURCE NOVEL CAME ABOUT FROM AN ANONYMOUS COLUMN ABOUT SINGLE LIFE.

In the foreword of Bridget Jones’s Diary, author Helen Fielding wrote about how she came to conjure up the story: “The Independent asked me to write a column, as myself, about single life in London. Much as I needed the money, the idea of writing about myself in that way seemed hopelessly embarrassing and revealing. I offered to write an anonymous column instead, using an exaggerated, comic, fictional character. I assumed no one would read it, and it would be dropped after six weeks for being too silly.”

2. SEVERAL CHARACTERS ARE BASED ON PEOPLE IN HELEN FIELDING’S LIFE.

These include Jude (Tracey MacLeod) and Shazzer (Sharon Maguire, also the film’s director). In a column for the Evening Standard, MacLeod described how she didn’t even realize she inspired part of her best friend’s story until Fielding’s book launch party. “At the launch party for the first Bridget book, I was cornered by a smug married friend, ‘So ... what's it like being Jude?’ she asked,” MacLeod writes. “I was outraged. Of course I wasn't Jude, with her self-help books and horrible boyfriend. My boyfriend wasn't anything like Vile Richard ... But as more people began to believe that Jude and Shazzer were thinly-veiled portraits of myself and Sharon, I secretly got to like the idea.”

3. TONI COLLETTE DECLINED THE LEAD, AND KATE WINSLET WAS CONSIDERED FOR IT.

Before Zellweger stole the show, Aussie Toni Collette and Brit Kate Winslet were up for the part. According to AMC, “Toni Collette declined the role because she was on Broadway starring in The Wild Party at the time, and Kate Winslet was considered but the producers decided she was too young.”

4. HUGH GRANT ONLY SIGNED ON WHEN RICHARD CURTIS WAS ANNOUNCED AS THE WRITER.

“The only reason [I was a hard sell] was because I didn't feel they had the script quite right for a long time,” Firth told Cinema.com. “And I kept saying, ‘It's not working. Just get Richard Curtis to come in and help rewrite it.’ Eventually they did, and as soon as Richard came on board, I signed on the dotted line. So that's all it was.”

5. RENÉE ZELLWEGER GAINED 17 POUNDS FOR THE PART.

Zellweger’s weight gain for the role had the media abuzz for a while. According to The Guardian, “In order to play the eponymous heroine in the film adaptation of Fielding's bestseller, the actress gained 17 pounds, consulting a dietitian and endocrinologist who devised a regime of three full meals a day, multiple snacks, and no exercise.”

6. ZELLWEGER WORKED AT PICADOR FOR THREE WEEKS.

Zellweger went full Method for her iconic role, and became a temporary employee of the Picador publishing house. “We came up with a plan: she would be Bridget Cavendish, Bridget for obvious reasons and Cavendish as she was to be passed off as the sister of Jonathan Cavendish, a friend of one of our company chairmen,” Picador publicist Camilla Elworthy told The Guardian. “That last bit at least is true, and no one was to know that Jonathan Cavendish was one of the film's producers.”

7. ZELLWEGER KEPT A PHOTO OF JIM CARREY ON HER DESK.

While working at Picador, Zellweger kept a picture of Jim Carrey on her desk—which made her alter ego Bridget Cavendish seem like some sort of obsessed fan. “Under the name Bridget Cavendish, she answered phones, served coffee, and made photocopies—without being recognized by any of her co-workers, who offered career advice and wondered privately why she kept a photo of Jim Carrey (her then-boyfriend) on her desk,” noted Hollywood.com.

8. ZELLWEGER INVITED HER BOSS AT PICADOR TO BE AN EXTRA ON SET.

In Camilla Elworthy’s write-up for The Guardian, she noted how she became a part of the production. “Renée sent me a thank you letter and gift after she'd gone and I have seen her a few times since then," Elworthy wrote. "She invited me on to the film set one day. She informed me that I had to stick around and be an extra and made sure that I was put somewhere that I would be seen ... As a result, half my head can be seen for half a nano-second in the launch party scene.”

9. THE EPIC FIGHT SCENE BETWEEN GRANT AND COLIN FIRTH WASN’T CHOREOGRAPHED.

You can thank the two actors for the hilarity of the iconic scene. In a Vulture article about the greatest fight scenes in movie history, writer Denise Martin recalled the improvised spar, writing, “No stunt coordinators. No elaborate choreography. Just a perfectly realized wimp brawl between two upper-middle-class Englishmen coming to awkward fisticuffs in front of a Greek restaurant.”

10. FIELDING ASKED FRIEND SALMAN RUSHDIE TO CAMEO IN THE FILM.

Recalling how he came to be part of the film, famed novelist Salman Rushdie told Texas Monthly, “Helen Fielding, the author of the book, is an old pal of mine, and she asked if I’d come along and make a fool of myself, and I said, ‘Why not?’”

11. GRANT DIDN’T HEAR ZELLWEGER SPEAK IN HER AMERICAN ACCENT UNTIL THE FILM’S WRAP PARTY.

Zellweger was so engrossed with Bridget Jones that one of her leading love interests didn’t meet the real actress until the end of the shoot. “Not once did she stop speaking with that accent, until the wrap party,” Grant told Cinema.com, “when suddenly this weird ... Texan appeared. I wanted to call security, I didn't know who the f*ck she was!”

15 Surprising Facts About Scarface
Universal Home Video
Universal Home Video

Say hello to our little list. Here are a few facts to break out at your next screening of Scarface, Brian De Palma’s gangsters-and-cocaine classic, which arrived in theaters on this day in 1983.

1. IT WASN'T THE FIRST SCARFACE.

Brian De Palma's Scarface is a loose remake of the 1932 movie of the same name, which is also about the rise and fall of an American immigrant gangster. The producer of the 1983 version, Martin Bregman, saw the original on late night TV and thought the idea could be modernized—though it still pays respect to the original film. De Palma's flick is dedicated to the original film’s director, Howard Hawks, and screenwriter, Ben Hecht.

2. IT COULD HAVE BEEN A SIDNEY LUMET FILM.

At one point in the film's production, Sidney Lumet—the socially conscious director of such classics as Dog Day Afternoon and 12 Angry Men—was brought on as its director. "Sidney Lumet came up with the idea of what's happening today in Miami, and it inspired Bregman," Pacino told Empire Magazine. "He and Oliver Stone got together and produced a script that had a lot of energy and was very well written. Oliver Stone was writing about stuff that was touching on things that were going on in the world, he was in touch with that energy and that rage and that underbelly."

3. OLIVER STONE WASN'T INTERESTED IN WRITING THE SCRIPT, UNTIL LUMET GOT INVOLVED.

Producer Bregman offered relative newcomer Oliver Stone a chance to overhaul the screenplay, but Stone—who was still reeling from the box office disappointment of his film, The Hand—wasn't interested. "I didn’t like the original movie that much," Stone told Creative Screenwriting. "It didn’t really hit me at all and I had no desire to make another Italian gangster picture because so many had been done so well, there would be no point to it. The origin of it, according to Marty Bregman, [was that] Al had seen the '30s version on television, he loved it and expressed to Marty as his long time mentor/partner that he’d like to do a role like that. So Marty presented it to me and I had no interest in doing a period piece."

But when Bregman contacted Stone again about the project later, his opinion changed. "Sidney Lumet had stepped into the deal," Stone said. "Sidney had a great idea to take the 1930s American prohibition gangster movie and make it into a modern immigrant gangster movie dealing with the same problems that we had then, that we’re prohibiting drugs instead of alcohol. There’s a prohibition against drugs that’s created the same criminal class as (prohibition of alcohol) created the Mafia. It was a remarkable idea."

4. UNFORTUNATELY, ACCORDING TO STONE, LUMET HATED HIS SCRIPT.

While the chance to work with Lumet was part of what lured Stone to the project, it was his script that ultimately led to the director's departure from the film. According to Stone: "Sidney Lumet hated my script. I don’t know if he’d say that in public himself, I sound like a petulant screenwriter saying that, I’d rather not say that word. Let me say that Sidney did not understand my script, whereas Bregman wanted to continue in that direction with Al."

5. STONE HAD FIRSTHAND EXPERIENCE WITH THE SUBJECT MATTER.

In order to create the most accurate picture possible, Stone spent time in Florida and the Caribbean interviewing people on both sides of the law for research. "It got hairy," Stone admitted of the research process. "It gave me all this color. I wanted to do a sun-drenched, tropical Third World gangster, cigar, sexy Miami movie."

Unfortunately, while penning the screenplay, Stone was also dealing with his own cocaine habit, which gave him an insight into what the drug can do to users. Stone actually tried to kick his habit by leaving the country to complete the script so he could be far away from his access to the drug.

"I moved to Paris and got out of the cocaine world too because that was another problem for me," he said. "I was doing coke at the time, and I really regretted it. I got into a habit of it and I was an addictive personality. I did it, not to an extreme or to a place where I was as destructive as some people, but certainly to where I was going stale mentally. I moved out of L.A. with my wife at the time and moved back to France to try and get into another world and see the world differently. And I wrote the script totally f***ing cold sober."

6. BRIAN DE PALMA DIDN'T WANT TO AUDITION MICHELLE PFEIFFER.

De Palma was hesitant to audition the relatively untested Pfeiffer because at the time she was best known for the box office bomb Grease 2. Glenn Close, Geena Davis, Carrie Fisher, Kelly McGillis, Sharon Stone and Sigourney Weaver were all considered for the role of Elvira, but Bregman pushed for Pfeiffer to audition and she got the part.

7. YES, THERE IS A LOT OF SWEARING.

According to the Family Media Guide, which monitors profanity, sexual content, and violence in movies, Scarface features 207 uses of the “F” word, which works out to about 1.21 F-bombs per minute. In 2014, Martin Scorsese more than doubled that with a record-setting 506 F-bombs thrown in The Wolf of Wall Street.

8. TONY MONTANA WAS NAMED FOR A FOOTBALL STAR.

Stone, who was a San Francisco 49ers fan, named the character of Tony Montana after Joe Montana, his favorite football player.

9. TONY IS ONLY REFERRED TO AS "SCARFACE" ONCE, AND IT'S IN SPANISH.

Hector, the Colombian gangster who threatens Tony with the chainsaw, refers to Tony as “cara cicatriz,” meaning “scar face” in Spanish.

That chainsaw scene, by the way, was based on a real incident. To research the movie, Stone embedded himself with Miami law enforcement and based the infamous chainsaw sequence on a gangland story he heard from the Miami-Dade County police.

10. VERY LITTLE OF THE FILM WAS ACTUALLY SHOT IN MIAMI.

The film was originally going to be shot entirely on location in Miami, but protests by the local Cuban-American community forced the movie to leave Miami two weeks into production. Besides footage from those two weeks, the rest of the movie was shot in Los Angeles, New York, and Santa Barbara.

11. ALL THAT "COCAINE" LED TO PROBLEMS WITH PACINO'S NASAL PASSAGES.

Though there has long been a myth that Pacino snorted real cocaine on camera for Scarface, the "cocaine" used in the movie was supposedly powdered milk (even if De Palma has never officially stated what the crew used as a drug stand-in). But just because it wasn't real doesn't mean that it didn't create problems for Pacino's nasal passages. "For years after, I have had things up in there," Pacino said in 2015. "I don't know what happened to my nose, but it's changed."

12. PACINO'S NOSE WASN'T HIS ONLY BODY PART TO SUFFER DAMAGE.

In the film's very bloody conclusion, Montana famously asks the assailants who've invaded his home to "say hello to my little friend," which happens to be a very large gun. That gun took a beating from all the blanks it had to fire, so much so that Pacino ended up burning his hand on its barrel. "My hand stuck to that sucker," he said. Ultimately, the actor—and his bandaged hands—had to sit out some of the action in the last few weeks of production.

13. STEVEN SPIELBERG DIRECTED A SINGLE SHOT.

De Palma and Spielberg had been friends since the two began making studio movies in the mid-1970s, and they made a habit of visiting each other’s sets. Spielberg was on hand for one of the days of shooting the Colombians’ initial attack on Tony Montana’s house at the end of the movie, so De Palma let Spielberg direct the low-angle shot where the attackers first enter the house.

14. SOME COOL TECHNOLOGY WENT INTO THE GUN MUZZLE FLASHES.

In order to heighten the severity of the gunfire, De Palma and the special effects coordinators created a mechanism to synchronize the gunfire with the open shutter on the movie camera to show the huge muzzle flash coming from the guns in the final shootout.

15. SADDAM HUSSEIN WAS A FAN OF THE FILM.

The trust fund the former Iraqi dictator set up to launder money was called “Montana Management,” a nod to the company Tony uses to launder money in the movie.
