TOKYO (AFP) - Scientists in Japan said Friday they had found a way to “read” people’s dreams, using MRI scanners to unlock some of the secrets of the unconscious mind. Researchers have managed what they said was “the world’s first decoding” of night-time visions, the subject of centuries of speculation that have captivated humanity since ancient times. In the study, published in the journal Science, researchers at the ATR Computational Neuroscience Laboratories, in Kyoto, western Japan, used magnetic resonance imaging (MRI) scans to locate exactly which part of the brain was active during the first moments of sleep.
