Fairytales

I kind of had fun creating my own little folklore for this one :) I'm curious to hear what kind of story you come up with!

For critique:
Are there too many details in the "things not to do"?
How does it flow?
What does the ending (the part in brackets) mean to you?

"The Witch over the Mountains"

Listen:
in her youth, one day she
flew up over the mountains,
turned her hair black and
went to dance with the goblin king.

Hush, children -
she is the earth itself.
Only eat your chestnuts after roasting,
and do not walk barefoot in the grass;
she reaches for you.
Beware her grasping soil fingers.

Take no apples or sweets,
trust not to luck or coincidence,
always close the garden gate,
and pick the bugs from wildflowers
before taking them home -
or else the goblin king will take you
to dance with him, too.

[Over the schoolyard:
a vulture of perched storm clouds,
a sudden, brief god
of cat's cradle strings
and splayed fingers.
And moist earth, like parted lips,
electric and open to the rain,
casts her spell.

A flock of seraphs
hovers at cloud-edges to watch.]
