one thing I know, is that whatever happens in dreams is not very representative of regular thinking (conscious, or awake thinking), it probably more hints of brute process, though wetwares probably more soft process.
I say brute process because the organ has to make adjustments, and it’s more the way it can.
it likely does adjustments more proximately, as in adjusting that influences this.
like, a crude example, if you don’t have a hammer use something else as a hammer.
I use the example of a hammer because some sort of force is required, but lots of things can be used as the force to alter structure, or maintain structure.
force is important aspect of dreaming, I remember when nineteen having a nightmare and thereafter taking some control of my dreams.
