More on unreality?

I don't think a spectacular magical very beautiful visuals are what is meant by my concept of unreality: more from the lack of such things.  When we are starved for that our mind's then could play tricks on us.  Then it is more likely that a person finds unreality in the years hence, maybe ten years later I don't know.  I can not say what the harm unreality does, how it works or anything, only that I feel sure that some people experience it.
