Muppet Movie ~ The Rainbow Connection
the main idea that comes to mind for me is how details of your dream
seem to match up with elements from the story of Noah and the arc.
the theme of a vast boat with animals onboard are direct connections.
the arc transported life during a turbulent time, and you may have
found yourself placed in the midst of something similar. the bolt of
lightning could signify you as having received heavenly energy, meaning
that you are entrusted with performing a holy duty (creating animal life
to be delivered wherever the ship is headed). Rudolf is associated with
leading the way in delivering the gifts to where they are wanted.
you don't quite get to the task of animal creation, but my guess is that
these are something akin to totems which will provide stability and
protection for the passengers when they disembark from their journey.
this is the age of aquarius.
