Of course, movies have known for years that this was possible–it’s just taken reality a while to catch up. Yes, science can see images in your brain, although for now it’s seemingly mostly proof-of-concept, and fairly limited. (No full color perfect simulacra of your dreams, yet.)
“Researchers from Japan’s ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person’s mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people’s dreams while they sleep.”
