Brain scans let computer reconstruct movie scenes
It sounds like science fiction: While volunteers watched movie clips, a scanner watched their brains. And from their brain activity, a computer made rough reconstructions of what they viewed.

Scientists reported that result Thursday and speculated such an approach might be able to reveal dreams and hallucinations someday.

Frightening and exciting possibilities: could be used as a self-discovery tool, and by psychoanalysts to unlock dreams, by the military to discover secrets, to establish guilt or innocence in courts of law…

And I am sure plenty of idiots will upload their dreams to Facebook, which in turn will enable advertisers to custom tailor commercials…
