What goes into creating dreams is a subject of great interest to almost everyone—including scientists. Here are some things which they've discovered can influence what happens after you close your eyes.

1. Sleeping on your belly gives you erotic dreams

People who sleep on their fronts are way more likely to have erotic dreams compared to those who go to sleep in other positions. According to a study, people who sleep on their tummy tend to get short of breath at night, and because of that, they often get dreams of wild sex. The people who sleep in such a position often experience racier dreams, like those involving being “tied up” or “locked up.” Another interesting fact to note is that most people who have experienced such dreams report that they also often involve a really famous personality.

2. Nightmares can be Shared/Genes influence your nightmares

Identical twins may usually have the same interests and habits, but scientists have discovered that their genetic basis is much stronger than anyone can imagine. It’s so strong that they can even experience nightmares on almost the same frequency. In a large study that involved nearly 2700 identical twins and 4200 non-identical twins, scientists found that identical twins are twice as likely to have the trait of having frequent nightmares as fraternal twins, which is both awesome and slightly creepy.

3. Earth’s magnetic field triggers weird dreams

It's possible that the Earth’s magnetic field has a profound effect on dreams in people. Psychologist Darren Lipnicki has been recording his dreams for over eight years and concluded that low geomagnetic activity caused weirder dreams, but when the geomagnetic activity was high, the dreams got more normal and sensible. His findings are strictly anecdotal but have provided the impetus for further controlled studies.

4. Black and white television gives you black and white dreams

Trying to think of a world in black and white might sound impossible, but some people actually do so in their dreams. A study published in 2008 by psychology student Eva Murzyn at the University of Dundee has shown that the type of television you watched as a child has a profound effect on the color of your dreams. Murzyn found that her respondents aged 55 and over had colorless dreams 20 percent of the time, leading her to believe that children who were exposed to black-and-white film and TV from ages three to 10 are more likely to dream in greyscale throughout their life. Other studies have shown that since the 1960s, 83 percent of the population dreams in color, a timeline that coincides with the advent of color TV—so it is possible that media has as much influence on our subconsciousness as life experience.

5. Different Cheeses affect your dreams

This might be a bit hard to digest, but a study has found out that different types of cheeses can affect your dreams. All cheeses contain an amino acid called tryptophan, which is helpful in normalizing sleep and reducing stress levels. A 2005 study conducted by the British Cheese Board discovered that the subjects who normally ate cheddar cheese dreamt more about celebrities; the people who ate Blue cheese (Blue Stilton) experienced bizarre dreams. Cheshire gave the best night's sleep, but it caused dreamlessness. The people who ate Red Lancashire had nostalgic dreams about their families and childhood and the ones who ate Blue Lancashire dreamt mostly about their work.

6. What you hear and smell influences your dreams

Our mind interprets the noise occurring around us while we’re asleep, and makes it a part of our dreams. This means that sometimes in our dreams we hear a sound from reality which is incorporated it a way that makes sense to our subconscious. For example, you may be dreaming that you are in a concert while your brother is playing a guitar during your sleep. In one study, researchers found that there was a significant difference between the dreams of the people who heard no music and the people who did. The ones who did hear reported that they had heard music in their dreams.

Even smells have an influence on dreams. Similar to noise, our brain interprets smells as a signal and incorporates it in dreams. For example, the scent of rose gave people pleasant dreams while the scent of rotten eggs gave weird dreams to people.

9 False Rumors With Real-Life Consequences

Don’t believe everything you read—or everything you hear. Unverified but plausible-sounding rumors have been the basis for violent death and destruction throughout history, whether or not the stories had anything to do with the truth.

In their book A Colorful History of Popular Delusions, Robert Bartholomew and Peter Hassall describe rumors as “stories of perceived importance that lack substantiating evidence.” They also note that the sociologist Tamotsu Shibutani describes rumors as “improvised news,” which tends to spread when the demand for information exceeds supply. Such an information deficit most often occurs during wars and other crises, which might explain why some rumors have had such dramatic results. Here’s a selection of some of the most interesting rumors with real-life results collected in Bartholomew and Hassall’s book.

1. KING LOUIS XV WAS KIDNAPPING CHILDREN.

In 1750, children began disappearing from the streets of Paris. No one seemed to know why, and worried parents began rioting in the streets. In the midst of the panic, a rumor broke out that King Louis XV had become a leper and was kidnapping children so that he could bathe in their blood (at the time, bathing in the blood of children was thought by some to be an effective leprosy cure).

The rumor did have a tiny kernel of truth: Authorities were taking children away, but not to the king’s palace. A recently enacted series of ordinances designed to clear the streets of “undesirables” had led some policemen—who were paid per arrest—to overstep their authority and take any children they found on the streets to houses of detention. Fortunately, most were eventually reunited with their parents, and rumors of the king’s gruesome bathing rituals were put to rest.

2. LONDON WAS GOING TO BE DESTROYED BY AN EARTHQUAKE.

Two small earthquakes struck London at the beginning of 1761, leading to rumors that the city was due for “the big one” on April 5, 1761. Supposedly, a psychic had predicted the catastrophe. Much of the populace grew so panicked that they fled town for the day, with those who couldn’t afford fancier lodgings camping out in the fields. One soldier was so convinced of the impending doom that he ran through the streets shouting news of London’s imminent destruction; sadly, he ended up in an insane asylum a few months later.

3. JEWS WERE POISONING WELLS.

Reports that Jews ritually sacrificed Christian children were not uncommon during the Middle Ages, but things took a particularly terrible turn during the spread of the Black Plague. In the 14th century, thousands of Jews were killed in response to rumors that Satan was protecting them from the plague in exchange for poisoning the wells of Christians. In 1321 in Guienne, France alone, an estimated 5000 Jews were burned alive for supposedly poisoning wells. Other communities expelled the Jews, or burned entire settlements to the ground. Brandenburg, Germany, even passed a law denouncing Jews for poisoning wells—which of course they weren't.

4. BRIGANDS WERE TERRORIZING THE FRENCH COUNTRYSIDE.

In July 1789, amid the widespread fear and instability on the eve of the French revolution, rumors spread that the anti-revolutionary nobility had planted brigands (robbers) to terrorize the peasants and steal their stores of food. Lights from furnaces, bonfires, and even the reflection of the setting sun were sometimes taken to be signs of brigands, with panic as the predictable result. Provincial towns and villages formed militias in response to the rumors, even though, as historian Georges Lefebvre put it, “the populace scared themselves.” In one typical incident, near Troyes on July 24, 1789, a group of brigands were supposedly spotted heading into some woods; an alarm was sounded and 3000 men gave chase. The “brigands” turned out to be a herd of cattle.

5. GERMAN-AMERICANS WERE PLOTTING SNEAK ATTACKS ON CANADA.

Canada entered World War I in 1914, three years before the United States did. During the gap period, rumors circulated that German-Americans sympathetic to their country of origin were planning surprise attacks on Canada. One of the worst offenders of such rumor-mongering, according to authors Bartholomew and Hassall, was British consul-general Sir Courtenay Bennett, then stationed in New York. In the early months of 1915, Bennett made “several sensational claims about a plan in which as many as 80,000 well-armed, highly trained Germans who had been drilling in Niagara Falls and Buffalo, New York, were planning to invade Canada from northwestern New York state.” Bizarre as it may sound, there was so much anxiety and suspicion during the period that Canadian Prime Minister Sir Robert Borden requested a report on the story, which the Canadian police commissioner determined to be without any foundation whatsoever.

6. THE INDONESIAN GOVERNMENT WAS HUNTING HEADS FOR CONSTRUCTION PROJECTS.

In certain parts of Indonesia, locals reportedly believe—or once did—that large-scale construction projects require human heads to keep the structures from crumbling. In 1937, one island was home to a spate of rumors saying that a tjoelik (government-sanctioned headhunter) was looking for a head to place near a local jetty construction project. Locals reported strange noises and sights, houses pelted with stones, and attacks from tjoelik wielding nooses or cowboy lassos. Similar rumors surfaced in 1979 in Indonesian Borneo, when government agents were supposedly seeking a head for a new bridge project, and in 1981 in Southern Borneo, when the government headhunters supposedly needed heads to stabilize malfunctioning equipment in nearby oil fields. Terrified townspeople began curtailing their activities so as not to be in public any longer than necessary, although the rumors eventually died down.

7. POWERFUL APHRODISIAC GUM WENT ON SALE IN THE MIDDLE EAST.

In the mid-1990s, the Middle East was home to some alarming rumors about aphrodisiacal gum. In 1996 in Mansoura, Egypt, stories began spreading that students at the town’s university had purchased gum deliberately spiked with an aphrodisiac and were having orgies as a result. One local member of parliament said the gum had been distributed by the Israeli government as part of a plot to corrupt Egyptian youth. Mosque loudspeakers began warning people to avoid the gum, which was supposedly sold under the names “Aroma” or “Splay.” Authorities closed down some shops and made arrests, but never did find any tainted gum. Similar rumors cropped up the following year in the Gaza Strip, this time featuring a strawberry gum that turned women into prostitutes—supposedly, the better to convince them to become Shin Bet informants for the Israeli military.

8. SORCERERS WERE PLAGUING INDONESIA.

In the fall of 1998, a sorcerer scare in East Java, Indonesia, resulted in the deaths of several villagers. The country was in crisis, and while protests raged in major cities, some in the rural area of Banyuwangi began agitating for restitution for past wrongs allegedly committed by sorcerers. The head of the local district ordered authorities to move the suspected sorcerers to a safe location, a process that included a check-in at the local police station. Unfortunately, villagers took the suspects’ visits to police stations as proof of their sorcery and began killing them. Anthropologists who studied the incident said the stories of supposed sorcery—making neighbors fall sick, etc.—were based entirely on rumor and gossip.

9. OBAMA WAS INJURED BY A WHITE HOUSE EXPLOSION.

These days, rumors have advanced technology to help them travel. On April 23, 2013, a fake tweet from a hacked Associated Press account claimed that explosions at the White House had injured Barack Obama. That lone tweet caused instability on world financial markets, and the Standard and Poor’s 500 Index lost $130 billion in a short period. Fortunately, it quickly recovered. (Eagle-eyed journalists were suspicious of the tweet from the beginning, since it didn’t follow AP style of referring to the president with his title and capitalizing the word breaking.)

An earlier version of this story ran in 2015.
