I believe that I have found the reason for naturals. Here is my explanation.


Consciousness

I believe there are 2 levels of waking consciousness. Here are the explanations for both.

Autopilot

I believe that most people go about there day as not being fully aware of what's going on around them. A sort of autopilot.
An example of this would be waiting for an event sometime in the future. When you think about it, it seems far away. But when it finally arrives you feel as if time went by really fast.I have an experiment for you to try that will take only a few minutes or so. I want you to get up from the computer and get a glass of water, and only think about getting the glass of water and the things you need to do to accomplish this act. Leave now.
Not that you're back did you think about only the glass or did your mind wander a bit? Did you think about where you were putting your feet or did you just walk there with out thinking?
This state of just acting and not really thinking about what you're doing is the autopilot frame of mind.
This is the way we think in normal dreams. We just go about our dream activity not thinking about what we are doing.


Higher awareness

There is a second stage of consciousness where one becomes more aware of things going on around them. At least with me I get hit with this second level of thought every once in a while and when that happens I seem to forget about things going on in the future or in the past and focus only on what's going on at that exact moment.
As an example, when you become lucid you can only think about what you're doing or going to do, and if you waver from this frame of mind you lose lucidity and re-enter the classic dream state.
I believe that naturals are in this sort of higher awareness state most of the time if not always.

conclusion
I think that if someone could train their mind to be in the hyper aware state they could constantly have the level of awareness in their dreams to consistently realize they're dreaming.



I am open for any kind of comment, be it good or bad. I would also like any information naturals could add on this subject.
