Didn't really know where to post this but here seems like the best place, anyway recently I have been thinking about the possibility of a dream recorder, Which could capture video from a first person view and also perhaps a third person view, with the addition of audio. I believe such things are possible if we could somehow have a machine that is able to generate images and audio as the user perceives the dream world and the machine can pick up on signals in the brain that correspond with things like objects audio such as speech if you know what I mean, what are your views on this and do you think it is also possible?
