Are there any incarnated individuals that can remember “everything” that happens during the entirety of their sleep cycle?

There are people who can remember the dreams coming up into higher levels of the subconscious that will be perceived by the conscious self upon awakening or drifting back and forth in a hypnagogic state. What is truly happening there is not connecting to the deep subconscious, but a hand-off of the dream from the deep subconscious to the upper subconscious mind which keeps the dream going and may alter it in some respect, but essentially is playing along. It is that upper subconscious mind dream experience that the conscious mind becomes aware of when sleep lightens and then can be recalled later. So these are important distinctions because the defect in communication with the deep subconscious is the greatest of human quandaries, but the phenomena, like we are describing in the sharing of dream material, clouds the issue in a sense and is so taken for granted nothing about the mind is seen to represent pathology even though much of it truly is. It is simply assumed to be the way things work and taken for granted it is what we experience naturally, being after all an animal that has evolved a higher level of intelligence. So one might well expect some rough edges and some incompletion in function since we are a work in progress presumably? The opposite is truly the case, that humans are wholly created beings and were created in a kind of state of perfection with respect to the intention to have an array of capabilities that were fully intact initially prior to the manipulations causing a diminishment.
