Those of us who practice dream yoga and the like know that, depending on damage, of course, isolation from outside experience and sensation can liberate the mind.
Even if you are not a practiced dreamer, you can easily imagine this by picturing yourself trying to concentrate while someone is talking, and the TV is on, and some music is playing, and a siren goes off, and a loud car goes by and a naked guy runs past your window, I'm sorry, what were you saying?
How can you even listen to your own thoughts? Now one by one take all that away. The sights, the sounds, even the feelings of the body. What might you imagine? What might you see? What might you experience? What might the distractions of dailing living have kept you from knowing?
How strong the pull of curiosity or even an inclination to alter and expand consciousness from children spinning to adults drugging themselves. To dreaming, how powerful; to an otherwise vegetative state, wow, how profound. What the science can do is incredible. I look forward especially to how this will physically map our very thoughts. Who knows? Maybe they'll find some really do come from the heart. Won't that be fun.
"Dreaming is perception unconstrained by sensory input. Perception is dreaming constrained by sensory input." ~~Stephen LaBerge
