Astral projection is when a part of you actually leaves your body and travels around. Also known as Out of Body Experience, or OBE, astral projection is not Controlled Remote Viewing. Let me explain the difference.
There have been documented cases of people who — while astral projecting — have been seen — and even photographed — in two locations at once. This is because we have an etheric body and a physical body. When your etheric body leaves your physical body and wanders around, it can be visible to animals and people with certain sensitivities. You are, in essence, like a ghost — even though you are still alive. Therefore, you are detectable.
Controlled Remote Viewing, on the other hand, is not at all like OBE. CRV is a written process, conducted with eyes open, speaking out loud, and writing everything that comes into your mind down on paper in a certain structure designed to separate imagination from true psychic perceptions.
CRV is known as "an interview and report methodology". It was designed for US military intelligence, and as such, it was imperative that this sort of remote viewing had to be undetectable.
If you are out of your body, spying on a secret military installation and the guard dog barks because he SEES you — you've blown your cover and the cause is lost.
With CRV, you can view, sense, hear, smell and experience everything at the targeted site, which can be anything, anywhere in all of Time or Space. BUT… you are literally undetectable, because no part of you is leaving your body.
So… What IS happening when a viewer is using CRV? One theory suggests that the subconscious mind is accessing the information from the Source, whether that be the "great big cosmic database in the sky" or spirit guides or God or whatever you want to call it. And as the subconscious mind accesses that information, it transmits to the Viewer's conscious mind through the body. The human body is the link between conscious and subconscious minds.
As you gain information, your conscious mind constructs a sort of virtual reality — a "copy" of the actual target. So the viewer experiences the target with all the smells, tastes, textures, and dimensions it offers - but is undetectable because he or she is not actually present at the target. Instead, it is as if the Viewer is on the Holodeck of the Starship Enterprise. It often feels very real to the Viewer, in fact! But it is merely a copy of the real target. Identical, but a copy.
I hope this clears up the difference between astral projection (OBE) and Controlled Remote Viewing.
