I asked this in the other thread: would tech like this enable you to view what someone is dreaming?



Yes, I think it would. I don't have a reference right now, but I remember reading a study a few years ago about how they detected V1 (primary visual cortex) activity during dreaming very similar to that when awake.


First you need someone who can sleep in an MRI.


People do that already. Some find it relaxing, oddly enough.
