Here Lucid Dreams, Astral Projections and Out-of-Body Experiences are all considered as a single phenomenon: the Phase. No theorizing or nonsense here. Only what works in practice and nothing else!
The essence of the Phase state (lucid dreaming and astral projection) is that a fully conscious person realizes that they are outside their physical body, which they only remember and does not feel in any way. Instead, they find themselves in a space that is just as real in terms of perception and structure, yet in which they experience sensations that are even more intense than those of waking reality. One can also walk, touch, hear, see, eat, experience joy or pain, and much more. In addition, one can now fly, walk through walls, morph into other creatures, and so forth.
