If a device was used to directly stimulate the areas of the brain that are associated with self-awareness and rational thought (frontal lobe), which have decreased activity during dream states, how well would that work? I think it's worth experimenting with.

This method could be a great alternative to lucid dreaming masks (NovaDreamer, Remee). Unfortunately, you'd have to be willing to put a hole in your skull.

What do you guys think?
