Dream recorder..

           
      Recording dreams to watch later as videos occurs quite frequently in science fiction. Notable examples of recording dreams and memories are in Final Fantasy, The Spirits Within, Paprika and The Excellent Strange Days. Recording dreams in science fiction usually leads to ethical and moral quandaries like does dreaming of murder actually count as a confession?
    Soon we will be able to find out and ask those questions ourselves if a group of researchers at the University of California are right. The team was able to reconstruct images of films just using brain scans. Basically, they subjected volunteers to hours of movie previews while simultaneously scanning their brain with an MRI machine. The team then used those brain scans to reconstruct images that could be traced back to a movie.
    Not just American researchers are working on this problem. A team of Japanese researchers has done a similar thing but has only created static images, not moving pictures. They also use a volunteer, an FMRI machine and sophisticated software, so this problem looks like there may be only one solution to it.
    All the experts agree that the technology could need decades of research before a functional dream or memory recorder is available. However, because there are two teams working on it, it could happen sooner than we think. Routine use of this technology could be decades away or with the right backing and money, it could be an iPhone app in five years time.
