theres no way to bridge the gap between reality and fiction other than your own senses. Those that would claim to be able to do that unconciously are literally delusional. You might think you are in control of your dream, but its the dream thats actually in control of you. But the dream is a product of your mind, and you are in control of your mind, right? Wrong. The mind acts upon its own accord once you leave concioussnes. Think of it as a form of autopilot. Its almost like a split personality. The part of you that is dreaming, is not real. Because you will wake up and be brought back to this place. Unharmed, unscathed and councious.
