Nibbana and correct view of Vijnana and Jhana

My Vijnana view from advaita Vedanta is deep and ingrained, it is false I know it but I need help to improve it because I read long time about conciousness the self I read much like these things like this : what about Consciousness. Have you ever experienced Consciousness without Being? For Consciousness to be known, it must be present. The reason we can say ‘I am,’ is because we know that ‘I am.’ And that which knows ‘I am’ is by definition, present, that is, being. I ceary now undertand that all these views are wrong. Honestly I knew it then to!. But had no other option. To my questions ... 1 ) When one experiences Nibbana is Nibbana experienced as in subject object relationship from the perspective of a subject or maybe there is no subject nor object during Nibbana like a state that transends that duality, In short what is happening in Nibbana what is the correct undertanding of what is happening. 2) Also more clarification needed regarding vinjana from my last question. Conciousness can be aware of itself you said, When I see something I (the mind) know what I am seeing. Isnt the knowing of what I am seeing " the knowing of what is seen and not conciousness conciousness of itself. Is conciousness conciousness of conciousness just the fact that there is the knowledge of what is happening, and is this not a thought and not conciousness conciousness of conciousness. Maybe I do not know because of my advaita even what conciousness conciousness of conciousness is so what is it. Isnt conciousness only an activity of cognizing with no cognizer. What am I missing. In which way would the conciousness of seeing imply conciousness conciousness of conciousness. 3) Also the experience of conciousness being concious of conciousness in advaita they say to experience this the same way you cannot take a step towards yourself beacuse you are already standning where you are the same way your attention cannot find conciousness as an object "relax your attention from all objects and that nothingness is conciousness awareness of itself" or ask yourself am I aware. (Do you agree that this relaxing your attention from all objects into a objectless-nothingness state is conciousness awareness of itself?), they say it seems like nothing from the point of view of the mind which knows only objects in subject object relationship while conciousness knowledge of itself is without subject or object. 4) They describe the state of relaxing our attention from all objects to come to the nothingness state as aware-being or the presence of that which is aware so they say awareness is knowing but it also IS it exists the knowledge of our own existence the knowledge I AM is conciousnessnes knowledge of itself "I know that I am" I know this is wrong view but please clarify why this nothingness state has nothing to do with how it is described. 5) When you said infinite conciousness in your last answer I suppose that doesnt include something metaphysical like infinite in space ?. 6) Also what struck me from your answer and is different from what I read and you said in the Jhana of infinite conciousness there are mental factors participating or enabling the infinite conciousness Jhana which shows this is not a blank state of nothingness , but a state you "built" up with intention,attention,perception etc am I right about this. This means if I or the mind is percieving this state I think that means that while I am percieving this state of infinitude of conciousness I am aware percieving the state of infintude of conciousnes (it is tricky because ifinitude to me indicates a infinite state where there is no mind or subject to know it) (I may be wrong) but as you described it (if I understood it) percieving this Jhana is something while we do it we know that we do it. Not like in advaita where when we relax attention from all objects and come to a nothingness we dont know anything about that state of nothingness in Buddhism this state seems to be something that during that state we are in it and percieve that state as an object to us as opposed to advaita which says there is no subject nor object when we relaxed attention from all objects and come to that state of nothingness. Huh this was not easy to understand for you if you have any questions about what I said please I understand it is complicated I am more than willing to clarify. please do not refer to me to other similar questions I saw other people having the similar question as I have but I couldnt find the satisfying answer. Once again thank you.
