thanks, SBC. The relevance to this thread compels me to repeat myself.
People who train themselves can induce and control their lucid dreaming. It is a capability all of us has but few of us even know about. You have the capability to shape your world, including the world in which you are awake and, indeed, you do shape your world. Your perception is your reality and your perception is shaped by your upbringing and things you have learned on your journey through life. Strange and wonderful things, things that no-one else experiences, intensely personal experiences (such as God speaking to you, for example) can exist in your mind because of its capability to go in between lucidity and dreaming. If you are disposed to a belief in the supernatural, your brain will be disposed to seek out evidence of it and you will be disposed to interpreting what you experience as supernatural even when you are wide awake.
