I must thank Jhanananda and all the others on this forum for their repeated guidances.

Lately, I've been struggling to reconcile a few insights.
1) I understand that the physical body is not me. It is in a way, me, but it is not really. Am I right to be thinking that the body is a mere interface for contact for the sense organs? And that the simple act of Desire has brought me into this world, merging me with the sense-consciousnesses and hence experiencing this world? I can see how if everyone is part of this "I", but currently in my experience, I am "me", the Ego. However, why is it that the present (or "being") feeling is only here in my experience? Why do I not see through the eyes of another being? Is there an explanation for that?
2) I understand that the past is a memory and the future is a fantasy. However, although the past, future or even the present cannot be clung on to, there is this succinct clarity of being in the present which makes it the "now". It is like the "I am". I can see from here how the 'self' can be met with by rejecting things by investigation, but I feel as if there is some kind of barrier blocking me from being "I". I feel like I am this light shining down on mental objects and hence making them tangible - abstract, gross, discrete, etc.
3) Thirdly, I cannot understand sleep properly. For example, I know lucidity in sleep is just like being aware that you are dreaming. However, this is in REM-sleep/light sleep. How about deep sleep? Is it the case that you should still be aware that you are unconscious? Do you definitely visit immaterial realms in sleep? I feel like I have a huge ton of unattained insights regarding this.
4) I understand suffering to only exist as a background. It is a polarity of suffering and pleasure. It is because we seek sensual pleasure that suffering exists. Pleasure is always in a background of pain. As such, as we move through life, we swing back and forth in pleasure and pain. However, what I don't understand is this. Is it the case that the 'me' still suffers and has pleasure while the 'I' disidentifies from the 'me' and hence is free from the stream of pain/pleasure?
5) What I don't understand about this point is that the lack of experience is also still an experience. For example, when closing our eyes, we still see 'blackness'. How does one get rid of that polarity completely from the senses? It is sufficient to go into third jhana? Would this experience be void? Or do we simply leave them as a 'background'?
6) I understand that consciousness is only birthed from duality and that awareness is primary, original and non-dual. However, I keep thinking from the scientific point of view that awareness is the "focus ability" of the brain - such as the reticular activation system/mid-brain at work, which denotes the functioning of an organic brain. Or would it be a reverse of cause-and-effect, such that the brain reflects what the awareness is doing instead of causing it?
7) I cannot seem to understand how one proceeds towards enlightenment. It is a void which is also full. Time, does it exist within it? It seems not to. Which brings me to the confusion between awareness and consciousness. Time exists in consciousness, but awareness does not seem to. Would be that the "I" is simply awareness? Or is it even more?

How does one operate if you are sitting in the background of things? It would be as if your body is moving automatically and responding to that world according to the conditions and effects. That would be the 'me' and not the 'I' right? What would I need to do... just remain in the 'I' and not care about the 'me' anymore? It seems a little counterintuitive considering the fact that I have to make right decisions, speeches and thoughts as I live the eightfold path.
