some of this has a feel of
the Wizard of Oz to it, like how it had
begun in sepia tone, and the magical land was where the color was.
the color is representing the vitality of life i think, and most of your
encountered scene lacked that quality.
the little girl may well be an aspect of yourself; observing. the rain of
crystals/roses appears synonymous with joyful love energy falling from
heaven to invigorate the landscape (but the residents are fearful).
you however celebrate this gift, and collect it.
to reach this scene, you'd needed to toil uphill... i'm thinking that your
life experiences in the interval between the dreams 1st appearance and
now
may have satisfied that ingredient, and that this may be why you're
recollecting the dream at this time [to see it's fruition].
i can't get a handle on who the young man is representing -- maybe he's
a proxy for all people of that village (at that particular situation in life).
it may be that you're wanting to enliven the village with your collected bounty.
the common beginning on a dirt road feels like you've had (virtually)
uncharted landscapes to explore... they begin lonely i'm assuming, without
others to interact with. this particular dream seems to provide you an
opportunity to imbue life in an impoverished/neglected area -- and it has
required that you expend efforts to achieve this position.
it's a blessing i'd say
