26 YEARS - YES 26 YEARS : THE AMOUNT OF TIME The Heroic Global Founder Framers of The World Students Society will spend asleep in an average lifetime.

21% - YES 21% is the proportion of time The Heroic Global Founder Framers of The World Students Society when sleeping, would spend dreaming.

AND 4 TO 6 CYCLES is the number of times the Heroic Global Founder Framers of The World Students Society will experience dream sequence every night.

The View Science : How dreams defend our brains.

WHEN HE WAS 2 YEARS OLD - STUDENT BEN STOPPED seeing out of his left eye. His mother took him to the doctor and soon discovered he had retinal cancer in both eyes.

After chemotherapy and radiation failed, surgeons removed both his eyes. For student Ben, vision was gone forever.

But by the time he was 7 years old, he had devised a technique for decoding the world around him; he clicked with his mouth and listened for the returning echoes.

This method enabled Ben to determine the locations of open doorways, people, parked cars, garbage cans and so on. He was echolocating : bouncing his sound waves off objects in the environment and catching the reflections to build a central model of his surroundings.

Echolocation may sound like an improbable feat for a human, but thousands of blind people/students have perfected this skill, just as Ben did. How could blindness give rise to the stunning ability to understand the surroundings with one's ears? The answer lies in a gift bestowed on the brain by evolution : tremendous adaptability.

Whenever we learn something, pick up a new skill or modify our habits, the physical structure of our brain changes.

Neurons, the cells responsible for rapidly processing information in the brain, are interconnected by the thousands - but like friendships in a community, the connections between them constantly change : strengthening, weakening and finding new partners.

NEUROSCIENCE calls this phenomenon brain plasticity, referring to the ability of the brain, like plastic, to assume new shapes and hold them. More recent discoveries in new science, though, suggest that the brain's brand of flexibility is far more nuanced than holding onto a shape.

To capture this, we refer to the brain's plasticity as '' live wiring '' to spotlight how this vast system of 86 billion neurons and 0.2 quadrillion connections rewire itself every moment of your life. The brain's livewiring allows for learning, memory and the ability to develop new skills.

Recent decades have yielded several revelations about live wiring, but perhaps the biggest surprise is its rapidity. Brain circuits reorganize not only in the newly blind but also in sighted who have temporary blindness.

In one study, sighted participants intensely learned how to read braille. Half the participants were blindfolded throughout the experience. At the end of five days, the participants who wore blindfolds could distinguish subtle differences between braille characters much better than the participants who didn't wear blindfolds.

Even more remarkably, the blindfolded participants showed activation in visual brain regions in response to touch and sound. In other words, the blindfolded participants performed better on the touch - related task before because their visual cortex had been recruited to help.

But such changes don't have to take five days; that just happened to be when the measurement took place. When blindfolded participants are continuously measured, touch-related activity shows up in the visual cortex in about an hour.

What do brain flexibility and rapid critical takeover have to do with dreaming? Perhaps more than previously thought. Ben clearly benefited from the redistribution of his visual cortex to other senses because he had permanently lost his eyes, what about the participants in the blindfold experiments?

If our loss of sense is only temporary, then the rapid conquest of brain territory may not be so helpful. And this, we propose, is why we dream.

In the ceaseless competition for brain territory, the visual system has a unique problem : because of the planet's rotation, all animals are cast into darkness for an average of 12 out of every 24 hours. Our ancestors effectively were unwitting participants in the blindfold experiment, every night of their lives.

So how did the visual cortex of our ancestors' brains defend its territory, in the absence of input from the eyes?

We suggest that the brain preserves the territory of the visual cortex by keeping it active at night. In our ''defensive activation theory,'' dream sleep exists to keep neurons in the visual cortex active, thereby combatting a takeover by the neighboring senses.

In this view, dreams are primarily visual precisely because this is the only sense that is disadvantaged by darkness. Thus, only the visual cortex is vulnerable in a way that warrants internally generated activity to preserve its territory.
