“The core principle is that our senses receive a far broader spectrum of messages than the narrow range we are taught to pay attention to. Our brains still receive many of those messages, but they are shunted into the subliminal and subconscious, and surface only as intuitions, emotions, premonitions, dreams, and visions. If we study those experiences not as illusions but as cues to other modes of apprehension, it might give us access to layers of reality we barely suspect, since the evidence for them is drowned out by the noise of ordinary perception.”
