The images the brain is processing while lucid dreaming are coming from standing wave images inside the fluid of pineal gland as seen by its retina, is that correct?
Wow... you are taking lucid dreaming seriously.
I've been wondering about the possibility of direct video input/output via the pineal gland. Currently video screen technology has reached the limits of the human eye. The use of the pineal gland could also allow for video input letting the user record their dreams and/or visions in HD as well as basic mouse & keyboard functions.
Current attempts at extracting video from the brain focus on analysing the electrical activity in the area of the brain that's currently processing images.
I think ECG technology and the other brain wave reading things are going to be wear that comes from. They just have to figure out binural beats for light and stuff.
