My apologies for not making myself more clear. Of course, you could be the devil's advocate, or Socrates' method...
As we see in the studies of neuroscience, particular thoughts can be mapped to particular areas of the brain. This means that certain neurons are triggered, I like the metaphor that Goleman uses, that these neurons are having a discussion with one another. However, these discussions, these thoughts that are being passed back and forth across the synaptic connections of the brain, are electric. Thus they have a physical form, as opposed to whatever imaginary abstract form one might be mislead to believe a thought consist of. That shows that there is a direct connection from the vibration or spectrum of existence of "mind" to "body".
I would say that during the "wet dream", these neurons begin to get excited and create electrochemical "substances"(excuse my ignorance here), what we call hormones, that "talk" to the neural receptors that connect to the sexual organ and create a release. This shows that the body and mind, the physical and not so-physical(that "substance") consistently work in unison, and the element or attribute, as Spinoza might say it, of "mind" can cause a physical act without the usually manual agents.
What Jung might refer to as the unconscious can cause you to ejaculate without you or your woman having to touch you, and will even give you a "theater" to envelope you in, emotionally(dimensionally?) placing your ego(um, self-recognizing attribute, psychological component) in a controlled psychic space of your own defined pleasures: the dream.
I don't want to get too far away from credible scientific assertions, especially knowing we are about to delve deeper into the metaphysical, but it is telling. There is obviously a way to mentally force the body to do things, in the same way that the body, through emotion or pain, can force certain thoughts directly to the amygdala, allowing it to intercept a choice from the neocortex.
Okay, here I'm going to use Freud's ego in a similar vein to Jung's conscious. I'm simply refering to the component of our compartmentalized individual self, that recognizes it self as being aware. When I say 'unconscious', unless stated, I will be referring to the infinite "library" of intelligent awareness, that our ego/conscious self is attatched to but not always aware of it's decision making. In the same sense that my heart is apart of me, and is me, and yet it is my heart, an entity of its own, yet without which the entity that is "me" finds it difficult to exist, the conscious that we recognize ourselves as having is only a small portion of the "consciousness" that our consciousness is connected to, thus we call it the unconscious, the part of consciousness that we know exist, or have concluded exist, and yet we only know it by its actions.
When a person "blacks"out, when a person is hallucinating, or in some sort of state of removed consciousness, the body and I would say mind, apparently some decision making goes on during these periods, are functioning without the aware component of the psyche, what Freud called 'ego'.
When that person comes out, or wakes up, when the self-aware, or the self-identifying part begins to go about the routine of living, they may notice a scratch here or there, their friends laugh at them or applaud them, depending what happened, how that autopilot, so to speak, worked for them. My point in this is that mind and body have stepped in and worked it out. This is because they are designed to. The ego is a farce, the god-head must eventually dissolve into the absolute in which it arrived from.
People go into comas, vegetable like states of "physical existence" due to certain physical traumas.
People faint at a sight that might cause them a psychological trauma if exposed too long.
People "black out" when the body is undergoing too heavy of a pain to bear "consciously."
There is some element, substance, whatever that knows all this, and it is apart of us, and we are apart of it.
And the human being seems to be the neuron of the universe, well, OUR known universe.
Why can't you feel the weight of the atmosphere until you start to rise or descend from the level you are currently on(think elevators)? What's removing the experience of one from the other, an ancient memory that didn't get the memo about tabula rasa?
Different contextual meanings or like the same contexts but still different meaning?
