Row, row, row your boat... back to the Matrix! Are you really just a butterfly dreaming that you are ... sometimes just a cigar?
When you're a baby sensory inputs are sent to your brain for processing. Gradually your brain sorts them out, learning to process and filter so that some inputs are routed to specialized processing nodes. These nodes hold a sort of committe meeting, and pass the results on to other nodes that formulate a response. You learn to recognize a smiley face and associate it with food and warmth, so when you start making noises and smack your lips and "mama" comes out the smiley face reinforces that behavior and you are on your way to learning language.
When you have pain, certain nodes become active. When you remember pain, those nodes become active again. And (If you are not a sociopath!) when you see others in pain the nodes again become active, and we say you have empathy.
The point is that each neural node, can sit on numerous committees, and more than one committee may think it appropriate to respond. Hence the symbolism of dreams. Hence poetry, which, if it is good poetry, causes response not just to the rational definition of words, but from associated nodes that call forth emotions. Hence also the attribution of intelligent agency to chance events, and faces of Jesus or Elvis on a water-stained wall or a piece of toast. It is in our interests to discern the reactions and motivations of others, so we may react to chance events as if they are caused by intelligent agencies. Hence, we postulate gods, demons, angels, spirits, fairies, "und so weiter".
From the attribution of intelligent agency to patterns of input we formulate the ideas of gods, spirits, and magic. From these arise superstition and religions, but also ideas that embody what most persons consider reality. Sometimes, in other words, the dream-world of partial signaling coalesces into something just as convincing and nearly as consistent as reality, (which can be pretty inconsistent at times, giving rise to much confusion) and having inadvertantly built part of the subconscious associations of the dream-world into our idea of reality, we thereafter resist its elimination from our world-view.
What I'm saying is that dreaming mind is not separate from the waking mind, but it is always acting, whether we are dreaming or not. We only become aware of the dream state when the major neural committees have ceased communicating with each other. (But the minor committees just keep on in idle gossip!)
