For the past day or so I was contemplating the question of whether or not someone who became so familiar and disciplined with lucid dreaming that they choose to live their lives inside their dreams - IE they would only wake up to eat and maintain minimal physical health, perhaps read up on some new information to propel their dreams, then go back to sleep. More so a complete reversal where your waking life means nothing and your dreaming life becomes your primary reality.

Has anyone been crazy enough to attempt this? Would it even be possible or would the person go insane?
