"Dreams can be monitored by brain activity " ? now there's a good one.
Yes. You can hook up somebody to a machine that monitors brain activity while they sleep and then tell from the activity graph on the monitor wheter or not that person is dreaming.
You can keep on denying it off course. But one can only wonder what you hope to accomplish by denying simple facts.
No, brain activity ( electrical energy that makes the machine go ) can be monitored,
but they will NEVER lay eyes on a "dream".
I never claimed that from such monitoring, one can tell what exactly a person is dreaming about specifically.
Just that dreaming clearly occurs in the brain, not outside of it.
You claimed that "dreaming" is a "spirit leaving the brain". If that were true, there should be no brain activity.
If dreaming, like consiousness, occurs in the brain, then there should be brain activity.
And there IS brain activity. Brain activity in area's of the brain that
make total sense even, in explaining dreams. Like how there is much activity in the visual cortex (allowing us to "see" in our dreams), and little in frontal lobes - preventing us to be overly critical of what we're seeing, which is why completely bizar and absurd things
in dreams don't register as such
in the dream. Yet as soon as we wake up, and the frontal lobes become active again, our first thought is "wow that was a freakishly weird dream!".
So what this point does, is completely blow your point out of the water.
No, dreams are not a "spirit" (whatever that is) "leaving the body" while asleep.
So no, going to sleep is not an example of a "mind" existing absent a brain.
So, try again: do you have a single example of a mind that exists absent a brain?
Wonderfull, thanks. You?
