Don, I don't think very many, if any specific "doctrine" about the structure of the non-physical can be embraced for a couple of reasons: One, we are talking about evolving consciousness that is in a state of continuous change, slow as that may or may not be. Two, the "beingness" of consciousness consists of countless individualized beings (you, me and everyone else) that have any number of probable opportunities open to each at any given moment, and since freedom of choice is intrinsic to us, allowance must be made for each individual's beliefs, inner quality of consciousness, etc. Otherwise evolutionary growth would not be possible.
I wonder, does it really matter where information comes from? I don't think so as long as the information/experience is helpful to a person's spiritual growth. Why does it matter if an ADC comes from the discarnate person or a "guide/helper" or from accessing memory held within the consciousness system itself if the contact made is beneficial to the person's spiritual growth? Why would a beneficial lucid dream experience be less than a beneficial NDE? It wouldn't since the entire purpose is to evolve consciousness in profitable ways by working with and helping individuals at their own level of understanding.
There are many, many realms of consciousness that exist as both non-physical and physical realities. Both types have their own rules of interaction. The non-physical has some structure, but not as most people think. There are no objects! Only symbolism... metaphors that represent culturally understood objects and ideals. The ones most of us experience are supportive environments to the ELS. Physical realities do have objective structure because of the constraints that arise from the laws/rules consigned to them such as time and space, mass and volume, as we know it in the ELS. Other physical worlds have their own physics, some are similar to ELS, others are very different and cannot be understood within our knowledgebase.
There are no non-physical fixed geographical territories except in the mind and memory of consciousness. They are real and can be visited and revisited and verified because they are representative of a shared cultural belief or as a supportive realm of consciousness. Essentially, they are metaphors that may be very helpful to us for communication with each other as long as it is realized that they are tools for describing experience. Otherwise, we can foster yet another belief system that can ensnare us. We want to progress beyond belief systems to further our spiritual evolution.
Rehab centers, hospitals, libraries, TV screens, computers, malls, houses, buildings, lakes, waterfalls, mountains, rivers, etc. are all within our knowledgebase and are easily understood so they make excellent metaphors for communication, especially when transitioning from a physical environment to a non-physical environment. It's what we know and perhaps it's the gentlest way to help us acclimate to a new way of life.

Here are some quotes from Van Dusen's "The Presence of Other Worlds" which I finally found hidden right in plain sight on my bookshelf. lol
(I paraphrased a bit for the sake of brevity.)
Quote:Page 81 - 82 "Our first state after death is like our state in this world, since we are then similarly involved in outward concerns. We have similar faces, voices, and character... This is why it still seems to us as though we were in this world unless we notice things that are out of the ordinary and remember that angels told us we were spirits when we were awakened." Heaven and Hell ~493
The closest analogy would be to the world of dreams, which also seems like the plain, ordinary, real world until one looks closer and pays attention to the differences. Like dreams, the spirit is now in a world of representations: he is beginning to meet his own nature in the things, people, and setting that surrounds him.
Page 85 - 90 The attitude that causes a drift toward heaven is in the feeling that there is a higher power and an effort to relate to it. This same spirit of humility and respect for the greatness of creation goes with an effort to be with others and to be of some use. By this, a person faces toward heaven. ...The one bound for hell serves himself first, last and foremost. By this attitude, he is cut off from the enlarging possibilities of heaven and becomes enclosed in concerns for himself over and above others.
"Essentially, spirits are affections or feelings, the inner or essential aspects of mind that underlie mere thought or memory. ...Since this is their nature, they are constantly breathing in a desire to know what is true, for the sake of constructive living. The Lord in fact sees to it that we love the constructive activities that suit our gifts." Heaven and Hell ~517
In many respects, the life of heaven cannot be understood as a simple extension of life in the world. Much of the character of the spiritual world is more nearly an extension of our inner experience. There is no time or space as we know it. ES said the ideas of time and space could impede our understanding of heaven. What corresponds to time is a change of state. The time of heaven is the always now time of the inner state.
Similarly, there is no space in heaven. What corresponds to distance is the feelings people have for each other. We also know the experience of being close to some and distant from others, regardless of the actual distances involved:
"People who are nearby are the ones in a similar state and the ones who are far away are in dissimilar states. It is why space in heaven is nothing but the outward states that correspond to the inner ones.
This is also why in the spiritual world an individual is present to another if only that presence is intensely desired. This is because one person sees another in thought in this way and identifies with that individual's state. Conversely, one person moves away from another to the extent that there is any sense of reluctance....
Whenever people move from one place to another, whether it is within their town, in their courtyards, in their gardens, or to people outside their own community, they get there more quickly if they are eager to and more slowly if they are not. The path itself is lengthened or shortened depending on their desire, even though it is the same path....
We can illustrate this by our own thoughts, ...for whatever we focus on intently in our thought is seemingly present...." Heaven and Hell ~193-196
What the spirit experiences is a reflection of inner experiences. Things in the spiritual world can be seen only by spiritual sight. What is seen and experienced is representative of the inner states. Spiritually rich inner states reflect in a surrounding that is gorgeous and rich. Barren inner states reflect in wretched surroundings. The spirit experiences what it is."
