Are we all delusionally insane? Math says time travel is possible, just as we walk around in space. But space & time are intertwined into space-time. Is precognition a form of time travel, That we all all doing it already but like a blind man at an orgy - we all have to feel ourselves around? Is our dreaming - the nonverbal part of our brain that talks in symbols - is the way to sense this reality that we are blind to when awake?
