In a nighttime experiment called the Dream Catcher, people’s dreams slipped right through the net. Looking at only the brain wave activity of sleeping people, scientists weren’t able to reliably spot a dreaming brain.

The details of that leaky net, described May 27 at bioRxiv.org, haven’t yet been reviewed by other scientists. And the results are bound to be heavily scrutinized, as they run counter to earlier work that described signs of dreams in neural data. The experimental design matters, because scientists suspect that dreams hold clues about the deepest mystery of the mind — consciousness itself. 

I find that more interesting than if they had found signs in the brain wave activity. To read more, click here.
