Maryjane,
"Typically lucid dreams or OBE's occur under situations of extreme duress."
This comment shows that your grasp of OOBEs (out of body experiences) is somewhat lacking. As for lucid dreams being caused by extreme duress... I have no idea what you mean.
There are two distinct types of OOBE. The NDE (near death experience) and the non-NDE OOBE.
I accept that the NDE usually occurs under physical duress. That it is a way of helping the consciousness deal with an extremely traumatic and painful condition or... is a natural occurrence when the physical body "dies".
So, the heart stops beating - an NDE occurs. The person describes leaving their physical body and hovering above it; they feel calm and experience no pain. The heart starts beating again and this same person describes their consciousness re-entering the physical body. Common situations being medical operations; car accidents; heart attacks; and general severe accidents or ill-health. The person has no control over their NDE.
OOBES, on the other hand are different. They can occur spontaneously, usually under no duress, or... can be consciously induced.
Let us focus on this second scenario. As I write, there are literally thousands of people around the world who are able to induce an OOBE at will, given the correct conditions. This has nothing to do with,
"occur under situations of extreme duress."
As an example, there is the American 'Monroe Institute' where you can study how to induce and experience an OOBE.
The Monroe Institute
The methods used are relaxation techniques. To change your state of consciousness, deep relaxation is, perhaps, the most common form. The Eastern yogis, meditation and yoga practices... these ways have been used for centuries to induce non-drug-related other states of consciousness.
Then there is the spontaneous OOBE. You are lying in bed going to sleep and the next instant you are looking down at yourself. You are so enthralled by the beauty of nature as you sit upon a hill at sunset, that you find yourself out of your body.
Then there is the physical safety valve. My mother, when she gave birth to me and my two brothers - each time the pain of giving birth reached its climax, she found herself out of her body and looking down at the birth procedure. She wasn't dying. This was simply a way of dealing with the extreme pain because out of your physical body, you feel calm and are at peace.
Going back to the induced OOBE, you have complete control over this. If interested in learning more about the topic then a quick Amazon book search for a) Robert Monroe b) Bruce Moen will tender 8 books on the subject. There are also a variety of other published books.
