BTCurious, that link reminds me of recent research that suggests a huge number of people previously considered vegetative actually have mental clarity. They didn't communicate with their eyes, but with different regions of the brain. They were asked to imagine, for example, playing tennis if the answer to a question was false, and asked to imagine following a map or rotating three dimensional objects if the answer was positive. Because these thoughts activate very different regions of the brain, the researchers were able to scan their answers in real time. I'll find a link, so we'll be prepared if Atlas goes comatose on us.

I almost killed myself in a lucid dream.

To this day, I honestly and fully believe that I would have also died in real life.
