" Not only did I rediscover every experience of my life, I had to live each unfulfilled desire as well—as though they’d been fulfilled. I saw that what transpires in the mind is just as real as any flesh and blood occurrence. What had only been imagination in life, now became tangible, each fantasy a full reality. I lived them all—while, at the same time, standing to the side, a witness to their, often, intimate squalor. A witness cursed with total objectivity. "

― Richard Matheson , What Dreams May Come
