I think I have a better idea with your input in post #21. Here is an article that deals with the 'internal pathway' of vision. For a layman like me, the details are too much, but you might understand them better.
The Primary Visual Cortex – Webvision
• I am more interested in beyond-the-physical ramifications of the mechanisms of open-eyed and close-eyed visions and dreams. I was puzzled if visual memories and dreams behind closed eyes are due to the visual cortex at the back of the head, how that could make the eyes move in what is called REM sleep. Here I found an article titled 'Proposed Mechanisms of Dreaming', that explains it:
Proposed Mechanisms of Dreaming
• I appreciate (though understand very little) all the phenomenal details of physical and neuro sciences involved in the brain activities, but all of them only help to explain what happens and how. As to whom it happens, it seems, even science is clueless as of now as this quote in the above article on dream says (italics added):
It is this series of activation and synthesis which creates the imagery we experience in the dream state. The forebrain receives the random signals from the brain stem and begins to assimilate the information into a coherent pattern. Presumably, the information received by the forebrain is spatially specific (hence the occurrence of 'rapid eye movement') and genetically programmed.
Who is this 'we', who experience the dream state? If it is just a part of the brain, why not say 'the brain experiences in the dream state' and add that 'there is no 'we' or 'I' as subjective consciousness, beyond the brain'?
Here is another paper on dreams:

The felicity of creation and movement in our dream world is awesome. It would be difficult to believe, even for scientists, that all that happens only with the head.
