Actually this would be kinda scary... We can already detect brain activity with modern tech, so in the future it may be possible for this to progress to mind reading technology, and even at some point mind control. 0_0 Hopefully such technology would be used ethically and safely... It would be cool only then. I mean, if somehow we could put ourselves into a forced state of lucid dreaming structured by a computer, we could have things like Sword Art Online in real life!
