Last night in a dream

Last night in a dream, snow, amounts the size of clouds,
then there was a railway track, abandoned,
spiralling high above our northern town,
then I was driving a school bus full of seniors
on the empty railway track, going higher and higher until there was a stop,
sight-seeing perhaps, and all the seniors got out,
and turning around I backed the bus over the edge, and it fell, tumbling,
how long I don’t know,
long enough to assess the landing which I assumed would end me,
but it happened that the snow had banked up and my landing was soft:
and suddenly I was a child riding a colossal yellow sled down an immense hill
that seemed to stretch on forever,
having the time of my life,
and here the dream ends:
and it leaves me thinking about about how natural happiness is to us,
how the unconscious desires to bring joy out of a distressful event,
perhaps even, how the loss of control, how letting go, allows beauty and wonder to emerge from chaos,
it also leaves me worrying about all those seniors I left at the top of that snowy, towering mountain.
