Pretty soon not even your dreams may be private anymore. Japanese scientists have learned how to interpret what you’re dreaming about by measuring your brain activity while you sleep. This data can then be plugged into an algorithm that reconstructs your dream so that it can be played back for you when you’re awake, according to the journal Science. In other words, scientists have invented a sort of dream-reading machine. Before long, you may never have to worry about forgetting what you dreamed about ever again. You’ll be able to simply play your dreams back after you wake up in the morning.
The remarkable breakthrough makes use of a fairly straightforward idea: that when we visualize certain types of objects in our minds, our brains generate consistent neural patterns that can then be correlated with what is being visualized. For instance, when you imagine a chair, your brain fires in a pattern that occurs whenever a chair is visualized. An algorithm can then be used to tie the data from a brain scan to the appropriate correlated images. And voilà! Your dream can be reconstructed.
