hopping in on this for some clarification, because I jsut can't quite follow what you're saying here...
I don't think you're getting the other half of the message, which is that I am using the logic of the materialist, who says that the brain and the person are one and the same.
ok...
If the brain is active during sleep, then the person must also be active (ie; conscious) but he is not.
Well, there is activity. Bodily functions don't cease when you sleep, your heart beats, you breathe..
Why do you think the body must be active, and what is your definition of active.
The brain gets a wild card to create imagery as it pleases. The "I", (which is the brain) is nowhere to be found.
I'm have a sense of self in dreams. I feel that I'm me, in my dreams, not someone else, or a non-being. How much sense of "I": are you looking for here?
It is found only in the waking state, when consciousness resumes. Therefore, "I" is a product of mind, which is a product of consciousness.
I is a product of the mind, yes, not a product of consciousness. What aspect of being unconscious do you feel would prevent the brain from processing information to yourself?
All the brain is doing during sleep is using imagery from memory to create fantasy scenarios. IOW, what one dreams is not actually going in as in the waking state. It is all a concoction on the part of the brain.
No, did someone suggest what your dreaming is really going on?
EDIT as a side question, you do know that the body TRIES to move, as if the dream is real, correct?
The fact that our bodies are not up and running around while we sleep, isn't because of some part of our brain saying "it's ok, it's fake" because, we would, if we could... Or bodies actually can't really tell the difference between "dream scenarios" and real ones very well.
