I would like to share my thoughts and opinions on what the 'dream-mind' is about. I am not particularly educated on the subject, and may tend to ramble.
It's an evolved brain function that is based in self-survival going back to the earliest 'thinking' man. (I'm sorry if that 'rings' of Hubbardspeak) Before the mental healing REM lucid dream cycle occurs, the deepest sleep cycle at the Delta brain-wave level preceeds it. This is because mental wellness is irrelevant if not alive. Early man didn't enjoy the comfort, or safety, we now enjoy. A full restful nights sleep maybe wasn't that easy to come by. It takes roughly the same amount of time for most everyone to cycle to REM sleep, an hour and a half.
I've read the extremely deep Delta level is where almost miraculous physical healing takes place. Really fascinating things are being discovered going on with the body during this level of sleep. After the dream-mind has worked down to the Delta for physical healing, it rises back up to address mental healing at the Theta brain-wave level.
The lucid dream Theta brain-wave cycle of activity only last a few minutes to maybe 15 minutes or more. It should be noted scientist are discovering 'mixes' or a 'blending' of brain-wave levels. It is not you are in this level, then snap you go to another level. However, once you are in REM, you are IN REM. Your physical body becomes paralyzed, with only the eyes and maybe some 'twitch' movement allowed. This is because in the REM Theta mind 'world', there is no telling what your dream body will be getting into, and you will be experiencing it as really occurring. Your eyes are allowed to follow the 'action', and my theory of why they can move so rapidly is because in this alternate world, time is not limited to what we know as time. Time is a physical concept, and there is no 'physical' in the dream world.
What happens when you transition into the REM cycle is you become 'alive'. You have all your senses working. You are in an alternate reality your brain creates. You are weightless, you are not affected by any laws of physical realilty. You can float, fly, or pass through walls or ceilings. However, I mostly discover my dream body is walking or sitting when I become lucid in the REM cycle.
Usually my dream-mind is doing squat really. I've become lucid finding my dream body doing things as mundane as sitting at my desk going over and writing checks to pay bills.
Normally though, people tend to remember snipets of only the very powerful and emotional dreams, and can tend to think that is going on all the time. I find that is not the case personally.
Since becoming a poster here, I've found my dream body viewing OCMB. My dream body viewing OCMB has become one of my 'triggers' to become lucid. I usually use seeing my hands, or 'snapping' to the actuality I'm experiencing things that cannot be real.
If I have something 'bothering' me IRL, such as something that occurred at work, or with the people in my life, my dream-mind can be 'addressing' that. Sometimes my dream-mind is doing something I can't really place a reason for it doing.
I've seen enough to know that what is at the core of my dream-mind activity is dealing with my fears and deep concerns. An example. I had an embarrassing experience at work I didn't handle as well as I wished, and a person cannot back-up time IRL.
So my dream-mind 'replayed' the scenario with me acting in the manner I wish I had. What my mind was doing was trying to 'heal' my waking-mind of this 'trauma', albiet a superficial trauma comparatively speaking.
The end-product my dream-mind wanted was for me to be able to go to work the next morning not carrying the full-weight of my embarrassing experience. It didn't want me to feel I needed to avoid any people involved in that situations occurance. It wanted me to survive the 'ordeal' and function at my best.
When Ex Scientologist have Scientology dreams, the same basic experience is occurring I feel sure. They are working through the experience, and working on 'healing' themself.
Once a person learns to become aware, or 'awake' while in the REM cycle, they can begin to learn how to control the dream-world. That is a whole different thing.
The first time a person truly becomes lucid in the dream body, it will scare you beyond words. The realization you have an alternate life going on every night is overwhelming with the unknown fear of what is in that 'world'. Who is in that 'world' etc.. This fear and excitement will cause you to loose your 'focus' quickly, very quickly.
It takes time to work through that. When I say 'awake' in the dream body, 'awake' is not like truly 'awake'. You are of a 'split mind'. The Theta mind must be the level maintained, but with a thread of awareness with your waking mind. When in this experience, if you can remember your phone number, you are doing very well indeed. If you can think...6 X 7 = 42, you are getting there.
...anyway, once you have learned to become 'at home' in your dream body, you can do literally anything you wish to do, or go anywhere you want to go. What you do and where you go will seem more than real, but it is only all created in your brain. You are not going anywhere really. You can easily find the experience so real you want to believe you went 'there' and saw that, but you didn't.
I have to go to work, I know I rambled, I hope I have given something to think about, and hopefully this post will create others here to post about how they interpret their dream-mind has been helping them learn to 'deal' with their Scientology experience. That is what I am seeing all through this thread.
L o v e,
p.s. I have more I want to say about this and would try to keep it relating to Scientology.
