Scientists say they have found a way to get a glimpse of people's dreams.
"Our results show that we can predict what a person's seeing during dreams," says Yukiyasu Kamitani, a researcher at the ATR Computational Neuroscience Laboratories in Kyoto, Japan.
Philosophers, poets and psychologists have long shared a fascination with dreams. But Jack Gallant, a neuroscientist at the University of California, Berkeley says solving the mystery of our dreams is one tough problem.

Spilled crude oil is seen in a drainage ditch near evacuated homes near Starlite Road in Mayflower, Ark., on March 31. An Exxon Mobil pipeline carrying Canadian crude oil was shut off after it ruptured March 29, causing an evacuation of 22 homes.
Amber Bartlett was waiting last Friday for her kids to come home from school. One of them called from the entrance to the upscale subdivision near Little Rock, Ark., to tell her the community was being evacuated because of an oil spill. Bartlett was amazed by what she saw out her front door.
"I mean, just rolling oil. I mean, it was like a river," she says. "It had little waves in it."
Facebook users post more than 2.5 billion messages and updates each day, worldwide. All posted content must comply with the company's standards, which ban many forms of speech that, in the United States, are protected offline.
Corporations may have more control over online speech today than the courts. Executives determine which videos, pictures and comments are permitted and what art is allowed. Their rules govern billions of posts across the globe each day.
And those policies differ dramatically across Silicon Valley's big social platforms. Twitter calls itself the free speech wing of the free speech party and models its approach on the U.S. Constitution.
An international team of researchers announced in Switzerland on Wednesday that an experiment on the International Space Station may have seen hints of something called dark matter. The finding could be a milestone in the decades-long search for the universe's missing material.
Only a tiny sliver of stuff in the universe is visible to scientists; the rest is dark matter. Researchers don't know what it is, but they know it's there. Its gravity pulls on the things we can see.
U.S. farmers anticipate planting the most corn since 1936, a total of 97.3 million acres. Farmers are hoping to rebuild their corn supplies after last year's drought. Chad Hart, economics professor at Iowa State University, explains why farmers intend to plant high amount of corn this season.
