Scientists 'read dreams' using brain scans

Brain activity correlated with the images
 that people saw in their dreams

Scientists have found a way to "read" dreams, a study suggests.

Researchers in Japan used MRI scans to reveal the images that people were seeing as they entered into an early stage of sleep.

Writing in the journal Science, they reported that they could do this with 60% accuracy.

The team now wants to see if brain activity can be used to decipher other aspects of dreaming, such as the emotions experienced during sleep.

Professor Yukiyasu Kamitani, from the ATR Computational Neuroscience Laboratories, in Kyoto, said: "I had a strong belief that dream decoding should be possible at least for particular aspects of dreaming... I was not very surprised by the results, but excited."
