When in a dream, we take it for real,
and the experiences of the dream
as telling us a true 'knowing' about the dream-world.
But when interpreted upon awakening,
we see it as only a story of our character's mind,
and this 'knowing' as being simply a description of this mind
that made the dream-world.
The individual pattern or view-point is what's known.
Nothing is objectively known about the so-called things,
inhabitants,
or
possible reality of the dream.
