Things you didn't know about dreams

Reading and enjoying these below facts on dreams that will blow your mind

1. Dream tenure


An average human being spends 6 whole years of his/her life dreaming, from everydayfactsoflife.

2. Memory limit


There's a time limit to how much you can remember about your dream. Only within five minutes since you are up from your sleep, an average person's dream is forgotten and in just 10 minutes, 90 percent of the dream is gone with the wind. However, if awakened at the REM (rapid eye movement sleep) stage, that person is more likely to remember the dream.

3. Eyes don't matter


Blind people can dream. People who became blind after birth can see images in their dreams and those who were born blind dream as vividly, however, instead of seeing images, they use their other senses such as smell, sound, touch etc. to dream.

4. Dream Master


The good part is that you can often control your dreams. You can manipulate, twist and turn the beginning and the ending of your dreams like it's a movie being shot in front of you. It is called the "Lucid dreaming" (one is aware that he/she is dreaming) phase.

5. Entry level


Toddlers don't star in their own dreams till they are about 3-4 years old.

6. Dreams are for everyone


There is not one person who doesn't dream, except those who have psychological disorders. If you think you don't dream, it's just that you're forgetting your dreams. That might be one of the most awesome interesting facts ever.

7. Familiarity


You might not remember the person in your dream. However, a person only dreams of people he/she has encountered in life but it's impossible to keep track of thousands of faces that you come across each day.

8. Colour no bar


Not everyone dreams in colour and not everyone dreams in black and white. If a person grew up watching black and white television, he/she is more likely to dream in black and white. In a survey, it was revealed that 12% of sighted people ONLY dreamt in black and white and rest of the sample dreamt exclusively in colour. The number has gone down. Today, only 4.4% under-25-year olds dream in black and white, the change is being based (by scientists) upon the transformation from black and white television to colour media.

9. Symbol


You sometimes have the strangest of dreams - some scary, some worrisome and the rest absolutely angelic. Remember, these are all symbols for something or the other. There's nothing strange about these dreams because they are only talking in a symbolic language like poems. Check out my list of fun, weird and just plain amazing fact of life I have found.

10. Universal


It's not only you who dreams, animals dream too just like this leopard lost in his dreamworld after eating lunch. The best example is a dog, you will often see them twitching their paws as if they are running in their dreams.

Clouds and what causes they to form?

How much do you know about clouds and what causes they to form? Keep following this article if you want to get more about them


Clouds are made of tiny drops of water or ice crystals that settle on dust particles in the atmosphere. The droplets are so small - a diameter of about a hundredth of a millimetre - that each cubic metre of air will contain 100 million droplets.

Clouds will either be composed of ice or water droplets depending on the height of the cloud and the temperature of the atmosphere. Because the droplets are so small, they can remain in liquid form in temperatures as low as -30 °C. Extremely high clouds at temperatures below -30 °C are composed of ice crystals.

Enjoy our wide range of funny pictures with captions that can make a joyful day.

How do clouds form?

Clouds form when the invisible water vapour in the air condenses into visible water droplets or ice crystals. There is water around us all the time in the form of tiny gas particles, also known as water vapour. There are also tiny particles floating around in the air - such as salt and dust - these are called aerosols.

The water vapour and the aerosols are constantly bumping into each other. When the air is cooled, some of the water vapour sticks to the aerosols when they collide - this is condensation. Eventually, bigger water droplets form around the aerosol particles, and these water droplets start sticking together with other droplets, forming clouds.

Clouds form when the air is saturated and cannot hold any more water vapour, this can happen in two ways:
The amount of water in the air has increased - for example through evaporation - to the point that the air cannot hold any more water.
The air is cooled to its dew point - the point where condensation occurs - and the air is unable to hold any more water.

The warmer the air is, the more water vapour it can hold. Clouds are usually produced through condensation - as the air rises, it will cool and reducing the temperature of the air decreases its ability to hold water vapour so that condensation occurs. The height at which dew point is reached and clouds form is called the condensation level.

What causes clouds to form?

1. Surface heating - This happens when the ground is heated by the sun which heats the air in contact with it causing it to rise. The rising columns are often called thermals. Surface heating tends to produce cumulus clouds.

2. Topography or orographic forcing - The topography - or shape and features of the area - can cause clouds to be formed. When air is forced to rise over a barrier of mountains or hills it cools as it rises. Layered clouds are often produced this way.

3. Frontal - Clouds are formed when a mass of warm air rises up over a mass of cold, dense air over large areas along fronts. A 'front' is the boundary between warm, moist air and cooler, drier air.

4. Convergence - Streams of air flowing from different directions are forced to rise where they flow together, or converge. This can cause cumulus cloud and showery conditions.

5. Turbulence - A sudden change in wind speed with height creating turbulent eddies in the air.

The range of ways in which clouds can be formed and the variable nature of the atmosphere results in an enormous variety of shapes, sizes and textures of clouds. To find out more about different types of clouds and how you can identify them, read our cloud spotting guide.

Amazing facts about Gerbils for kids

Can you list some interesting facts about Gerbils for kids? Don't you know the answer? Don't worry, this writing will help you. Keep reading to know

Gerbils are mammals that are native to northern China. In 1954 gerbils arrived in the United States to be used in research and quickly won the hearts of lab workers who began taking them home as pets.


  1. Gerbils were originally known as ‘desert rats’ before they were introduced to North America and Europe as a companion species. Although they are rodents, they are a distinct group of animals from rats.
  2. Gerbils are able to shed their tail if it gets caught. This self-defence adaptation allows them to escape predators that are able to catch their tail as they try to flee. Their tails are around the same size as the rest of their body.
  3. Gerbils build extensive networks of underground tunnels. They spend most of their time in these burrows, only tending to leave to find food and water.
  4. Gerbils’ whole bodies, including their tails, are covered with fur. This is important for protecting them from getting sun-burnt in the hot desert regions.
  5. Gerbils have a quiet and calm nature. They are inquisitive and curious and not easily startled.
  6. When sensing danger, the normally quiet gerbil will let out a squeal and thump its back legs like a rabbit to warn others of the threat. Let’s discover some interesting science facts that will amaze you.
  7. Rather than using water, gerbils wash using sand. They roll around in the sand, which gets any debris off them and leaves them with a smoother and shinier coat.
  8. There are over 100 different species of gerbil. The largest being the Great Gerbil, Rhombomys opimus, which is native to Turkmenistan and can grow up to 16 inches long. The most common species kept as a pet is the Mongolian gerbil, Meriones unguiculatus. The Mongolian gerbil’s scientific name means ‘small-clawed warrior’.
  9. Gerbils are social animals, and live in groups in the wild. In domestic situations, unfamiliar gerbils are likely to be very aggressive to each other if forcibly introduced while still having contrasting scents.
  10. Gerbils are playful animals, and will often box and wrestle each other. Grooming is often carried out simultaneously here, illustrating that it is not an aggressive act. These dummy-fights can be vital for allowing young gerbils to learn to defend themselves in later life. It also helps maintain social bonds, although in adults such boxing can become a means of establishing rank in the dominance hierarchy.
Are you bored? Let’s have a quick look at our funny images that are bound to bring smile on your face.

The best collection of awesome Cow facts

Here are a handful of fascinating, little-known facts about some of the weirdest creatures: Cow and their best collection of interesting facts.

  • Cows have an excellent sense of smell. They can smell up to 5 miles away!
  • Cattle are herbivores that eat vegetation such as grass.
  • Cattle stomachs have four chambers which help break down what they eat
  • There are well over 1 billion cattle in the world.
  • Cattle are sacred in India.
  • In deep mud, cows can run faster than horses!
  • A cow has one stomach with four compartments. The rumen, reticulum, omasum and the abomasum.
  • Cow are ruminates meaning they can digest food that can normally not be digested.
  • Like a human’s fingerprints, no two cow’s spots are exactly the same.
  • A cow is pregnant for nine months. A calf is about 90 pounds when it is born.
  • There are an estimated 300 million cattle in India.
  • Young cattle are generally known as calves.
  • Like many other grazing animals cattle have one stomach which is divided into four compartments or chambers: the rumen, reticulum, omasum and abomasum. This allows them to digest grain and grasses most effectively.
  • Cattle have almost 360° panoramic vision. This helps them to see predators coming from any direction. Enjoy the best collection of animals facts on our site to widen your knowledge.

  • Cattle have an excellent sense of smell. They can detect odours up to five miles away. They can also hear both low and high frequency sounds beyond human capability.
  • The cow is a protected animal in Hinduism, and Hindus do not eat beef. Cows are honoured at least once a year, on Gopastami. On this day cows are washed and decorated in temples.
  • Mahatma Ghandi described a cow as “a poem of compassion”, also stating that “I worship the cow and I shall defend its worship against the whole world”.
  • The meat of cows is widely eaten by people across the world. Cows' milk is also drunk and used to make other products such as cheese. Many people who consume animal products would like to choose products from animals kept in higher welfare systems. However welfare labelling on products can be confusing. 
  • Adult females are generally called cows.
  • Adult males that are not castrated are generally called bulls.
  • Cattle are red/green color blind.
  • In the sometimes controversial sport of bull fighting, bulls are angered by the movement of the cape rather than its red color.
  • Cattle are farmed for a number of agricultural products including meat and dairy products.

Some facts and information about reptiles

If you are a person who love to know animal facts and want to know more, you are at the right place. Here is answers some information about reptiles them for your checking out.  

1. There are more than 8,000 species of reptiles on the planet, and the live on every continent except Antarctica (where it is too cold).

2. "Cold-blooded" is not the best way to describe reptiles. Their blood is not necessarily cold by itself. But they are ectothermic, which means they get their body heat from external sources. Reptiles cannot regulate their body temperature internally as humans do.

3. Reptiles are among the longest-lived species on the planet. For example, large tortoises such as the Aldabra tortoise can live for more than 150 years. Alligators can live nearly 70 years. Ball pythons, a popular type of pet snake, can live up to 40 years (consider that before getting one as a pet).

4. Most of the world's snakes (nearly two-thirds) are non-venomous. Only about 500 snake species are venomous, and of those only 30 - 40 are considered harmful to humans. In other words, less than 2 percent of all snakes are considered harmful to humans.



5. With regard to reptile fact #4 above, the opposite is true in Australia. There are actually more venomous snakes in Australia than non-venomous snakes. The inland taipan is one of the most popular of these venomous Australian snakes. Australia is the only continent where venomous snakes outnumber non-venomous snakes.

6. It is a fact that more Americans die each year from bee stings than from snake bites.

7. Certain types of snakes can go months without eating. This is especially true of the big constrictors, such as the Anaconda and the reticulated python. Snakes eat large meals (relative to their body size), and they have much slower metabolisms than we humans have. This partly explains how they can go so long between meals.

8. Most kinds of reptiles do not tolerate the cold very well. But the Blanding's turtle (Emydoidea blandingii) is sometimes found swimming under the ice in the Great Lakes region of the United States. 

There exists a lot of amazing creatures in our world that are bound to make you surprise. Do you want to check out our long and rich source of tigers facts in your spare time?

9. Snakes and lizards flick their tongues in the air to capture scent particles. They don't smell through their noses like you and I. Instead, the use their tongues to collect scent particles and then pass the particles over something called a Jacobson's organ to decipher the air around them. This is partly how reptiles hunt for food.

10. True to its name, the African egg-eating snake (of the genus Dasypeltis) prefers to dine on the eggs of other animals. It will swallow the egg whole, and then use tiny "spikes" extending internally from its spine to crack the egg open and swallow the nutritious contents. Lastly, it will regurgitate the unneeded egg shell in a neatly folded piece.

11. Contrary to popular belief, chameleons do not change their color to blend in with different backgrounds. Chameleons are naturally camouflaged with their surroundings (most are predominantly green to match their treetop environment). The fact is that chameleons change their color in limited ways, usually by brightening or darkening their skin. But these color changes are related to temperature regulation and emotional changes. A frightened or angry chameleon, for example, will become extremely bright in color.

12. The skulls of snakes are made up of many small bones that are interconnected in a flexible fashion. This is entirely different from a human skull, which is one solid piece. This allows snakes to expand their jaws and heads in order to eat prey items larger than their heads. A common garter snake, for example, could swallow a frog more than twice the size of its head. Large constrictors such as the anaconda can expand their jaws to an almost alarming degree!

13. Many people think that reptiles are slimy. But the fact is that reptiles do not have sweat glands like you and I have, so their skin is usually cool and dry. I have several pet snakes for example, and people who touch them for the first time always say the same thing: "Oh wow, they're not slimy at all."

14. The scales of all snakes (and many lizard species) are made of keratin, which is the same substance that makes up the hair and fingernails of humans.

15. Snakes shed their skin in relation to their growth rate. A young snake will shed more often because they typically grow fastest during the first two years of their lives. An older snake will shed less often as its rate of growth slows down

What is "Nightmare Machine"?

Here are some amazing news and facts about: What is "Nightmare Machine"?


The idea of artificial intelligence (AI) — autonomous computers that can learn independently — makes some people extremely uneasy, regardless of what the computers in question might be doing.

Those individuals probably wouldn't find it reassuring to hear that a group of researchers is deliberately training computers to get better at scaring people witless.

The project, appropriately enough, is named "Nightmare Machine." Digital innovators in the U.S. and Australia partnered to create an algorithm that would enable a computer to understand what makes certain images frightening, and then use that data to transform any photo, no matter how harmless-looking, into the stuff of nightmares.

The idea of artificial intelligence (AI) — autonomous computers that can learn independently — makes some people extremely uneasy, regardless of what the computers in question might be doing.

Those individuals probably wouldn't find it reassuring to hear that a group of researchers is deliberately training computers to get better at scaring people witless.

The project, appropriately enough, is named "Nightmare Machine." Digital innovators in the U.S. and Australia partnered to create an algorithm that would enable a computer to understand what makes certain images frightening, and then use that data to transform any photo, no matter how harmless-looking, into the stuff of nightmares. [5 Intriguing Uses for Artificial Intelligence (That Aren't Killer Robots)]

Images created by Nightmare Machine are unsettling, to say the least. Iconic buildings from around the world appear eroded and distorted within shadowy settings or amid charred and smoldering landscapes, glimpsed through what appears to be murky, polluted water or toxic gas clouds.

Nightmare Machine's faces are equally disturbing. Some of the subjects are almost abstract, but subtle — creepy suggestions of hollow eyes, bloody shadows and decaying flesh still cause unease. Even the lovable Muppet Kermit the Frog emerges from the process as a zombie-like creature that would terrify toddlers — and adults, too.

The primary reason for building Nightmare Machine was to explore the common fear inspired by intelligent computers, its trio of designers told Live Science. They wanted to playfully confront the anxiety inspired by AI, and simultaneously test if a computer is capable of understanding and visualizing what makes people afraid.

"We know that AI terrifies us in the abstract sense," co-creator Pinar Yanardag, a postdoctoral researcher at MIT Media Lab in Massachusetts, wrote in an email. "But can AI scare us in the immediate, visceral sense?"

The designers used a form of artificial intelligence called "deep learning" — a system of data structures and programs mimicking the neural connections in a human brain — to teach a computer what makes for a frightening visual, according to co-creator Manuel Cebrian, a principal research scientist at CSIRO Data61 in Australia.

"Deep-learning algorithms perform remarkably well in several tasks considered difficult or impossible," Cebrian said. "Even though there is a lot of room for improvement, some of the faces already look remarkably creepy!"

Once deep-learning algorithms understood the visual elements that were commonly perceived as spooky, they applied those styles to images of buildings and human faces — with chilling results


"Elon Musk said that with the development of AI, we are 'summoning the demon,'" co-creator Iyad Rahwan, an associate professor at MIT Media Lab, told Live Science about science facts.

"We wanted to playfully explore whether and how AI can indeed become a demon, that can learn how to scare us, both by extracting features from scary images and subsequent refinement using crowd feedback," Rahwan said. He added that the timing of their spooky experiment — close to Halloween — was no accident. It may be one of the most awesome infor from factoflife we’ve enjoyed.
 
"Halloween has always been a time where people celebrate what scares them," he said, "so it seems like a perfect time for this particular hack." 

"Our research group's main goal is to understand the barriers between human and machine cooperation," Rahwan said. "Psychological perceptions of what makes humans tick and what makes machines tickare important barriers for such cooperation to emerge. This project tries to shed some light on that front — of course, in a goofy, hackerish Halloween manner!"

And if you're brave enough, Nightmare Machine could use your help to learn how to become even scarier.

The project's creators used deep-learning algorithms to generate frightening images of dozens of faces, tweaking the results to make them look even more disturbing. Nightmare Machine visitors can vote on these so-called "Haunted Faces," to help the algorithm "learn scariness," according to instructions on the website.

Teaching a computer to be more terrifying — what could possibly go wrong?
