My wording can be poor, my apologies! When I say they are necessary, I do not mean that they are necessary for anything else, but they happen as necessary as one moving ball knocks another ball which moves.

I think what you mention with metabolizing non metabolized content resonates with me in a similar way, and is more or less what I am getting at.
I agree with you about ñanas being more powerful in dreams. It is like when we are dreaming we sometimes 'forget' to break up experience with discursive thoughts. Had a very strong A&P experience a few nights ago, it was like a feedback loop of experience, which is something that would be interrupted in waking life.
Working on dreams sounds like a good idea, I try make sure I don't forget them through the day, however I believe that simply the act of having the dream has a useful effect of balancing potential, which is why we can remember things that we might not have remembered well before, like a brain defrag.

I've slept well the last couple of nights thank you
