Moran Cerf, a researcher at New York University who is currently working in the field of consciousness and emotions, believes he has a system that could one day detect and record the subjects of your dreams.*
However, as any fule kno, the correct auteur to use in this reference is Wim Wenders:
As this linear chase snakes itself around the world, the nuclear satellite is shot down, causing an EMP effect that wipes out all unshielded electronics worldwide. The characters wind up in a hidden cave in the Australian Outback, where the recordings are played back. After the death of the hitchhiker's mother during the transition between the first and second phases of the plot, his scientist father discovers a way to use the device to record human dreams; by this time the second phase of the plot has fully commenced. Several of the central characters become addicted to viewing the playback of their own dreams
No need to thank me, I'm just happy to be of service. I do recommend you see it if you ever get the chance, it's one of the strangest and most beautiful films you'll ever see.
But before you get too excited about playing back last night’s slumber-vision in high definition, Cerf’s system is far, far more humble, and is a far cry from the systems seen in science fiction movies. Instead of watching your dream on a display like Red Dwarf's "dream recorder", the method simply monitors neural activity in your brain.
