N) When those reading this dream, do you each dream a different dream, or is one dream created within your brain which you all see? (Or is one dream created within your brain which only one or only some see/s, or multiple dreams, one or some or all with more than one person observing, or... er. *stops rambling* [insert general request for information here]) *curiosity*
