Consciousness

[Paleophyte]

So something from your experience. Not so much speaking a language that you couldn't comprehend.

Right....it was a very subjective dream. Kind of enjoyable too. Dreams are so interesting.

So nothing new. Just what you went to sleep with. That's because dreaming is not "when your brain is interfacing with other realities through varying energetic frequencies." The only reality that you're interfacing with is the one that's inside your skull.

Do you think different types of dreams could be activating different parts of the brain?

Not really. It's known that the prefrontal and cerebral cortex, brainstem, hippocampus, and amygdala are active during dreaming. But it's wrong to say that dreams are 'activating' these areas of the brain. It's probably more correct to say that activity in these areas produce dreams. However, this is not settled science. There's a lot we still don't know.

According to The Emergence of Dreaming by William Domhoff (Oxford University Press 2018), "REM sleep activation turned out to involve a more specific network [rather than the whole brain], with special emphasis on regions within the medial prefrontal cortex and lateral temporal cortex, as well as more posterior parts of the brain, such as the temporoparietal junction. The deactivation during REM sleep of the dorsolateral prefrontal cortex [DLPFC], which is an important basis for working memory, task-oriented thinking, and the experiencing of emotion, along with the deactivation of the primary sensorimotor cortex and the primary visual cortex, were especially striking." (pages 167-168)

In other words, the executive part of our brain which underlies self-consciousness and working memory, as well as those regions which process incoming information and coordinate outgoing motor commands, are turned off.  What is active is a collection of areas now referred to as the default circuit, which is also active during mind-wandering and day-dreaming while awake, as well as the secondary sensorimotor cortex and the secondary visual cortex, which are involved in creating motor commands and visual imagery in the brain.

While the brainstem does control the dreaming state, it is not itself a conscious part of the brain, so it does not dream.  The amygdala contributes to emotional experiences while dreaming, and can be abnormally activated in dreaming in those who suffer from PTSD.  However, without the DLPFC being activated, our emotional responses in dreaming are often muted.  In other words, we do not react as emotionally to some circumstances in our dreams as we would if they happened in waking.  According to the author, this is one aspect of the cognitive deficiency of the dreaming brain, without all of its functions working.

Interestingly, those people who become blind before the ages of around five to seven do not dream visually, though they dream about other sensory aspects of the world.  Those who become blind later can dream normally even without waking sight.  Studies of the dream reports of children at different ages also support the idea that dreaming is a learned cognitive ability rather than an ability inherent in the brain. We learn to dream in waking, although dreaming overlays an automated housekeeping process controlled by the brainstem.

Probably more accurate to put it the other way around. Activity in different parts of the brain might produce different types of dreams. That said, it sounds like it's all fairly similar. The brain's in a resting state without much external input, so you aren't going to get many of the more interesting areas showing a lot of activity.

[Alan V]

Activity in different parts of the brain might produce different types of dreams.

As one example, lucid dreaming, during which we realize we are dreaming, has been shown to be correlated with a partial reactivation of the DLPFC.

Also, there is a certain threshold, a certain amount of activation which is required to support dreaming. Even NREM periods late in the sleep cycle can have enough activation to support dreaming very similar to REM dreaming, though reports are shorter.

However, I would say from my reading that beyond the activation of certain areas, dreaming is a combination bottom-up and top-down process, a self-reinforcing loop.

Were they speaking Korean? Was it actually North Korea or something that your brain concocted from splinched geography, stuff you saw on TV, and unchecked emotions?

It was like a "Deadman Wonderland" type scenario, if you know what that anime/manga is.

[The Grand Nudger]

I once dreamt that I was a cold mist killing joggers. Tough dream to wake up from, so much fun.

I once dreamed I was a middle-aged Chinese couple looking to adopt a caucasian baby....

Unconsciousness cannot cause consciousness. The Principle of Causality states that the Cause is always (yes. always) greater than the Effect.

Yeah, that’s not only not what it says, it’s also not true. The patch of ice on a roadway is in no sense greater than the six car pile up it causes.

Please stop trying to use science to justify your particular brand of magic.

Collusion (cause), wreck (effect).

The Cause is always greater: 1. Initiates the transaction. 2. Linked to fundamental forces.
