Below is a thought. Being currently engaged in the world with others, I am able only to share my thoughts, and not to comb through it for errors.
If you will read this, I ask that you read it with the above in mind.
Dreaming is like the act of Imagination, only longer and without the sensory input of waking life.
When I think about something, and the thought, concept, idea of a thing or circumstance within a particular context, environment, affected by such and such expectations, beliefs, I can become lost in it.
When my attention returns to the world as we communally experience it, there is an imperceptible transition to what I just “saw”, thought, felt to what now affects me as real as anything I have ever known.
From this I postulate that what one experiences in a dream (the non lucid variety), is like a line of thought free to follow what end is afforded to it.
I am saying that the experience of being detached from external stimuli produces a similar effect to what one may experience in a sensory deprivation chamber.
What makes dreaming particularly unique from mere imagination is the passive intent of the act of sleeping, the disconnect of our intentions from that of our muscles.
Dreaming seems to be a thought run amok, lost in itself. Without information flowing in, without the minds need to persevere the self, the mind creates a world of laws, circumstances, quaila in accordance with, or relative to that which is experienced in life in the world.
Just a thought.
Hot out if the mind.
