What are some metaphors for winter?

Answer 1

Winter is a time of reflection - everything dies off or goes within it itself to grow and be renewed once spring is here again. Bears and other animals hibernate, plants shut down and store energies to feed off of until the warmth returns... We as people tend to celebrate being indoors with our families and friends, (Christmas, Hanukkah, etc) being warmed by fires built in the fireplace and in our hearts (building our foundational relationships). It can also be a time where we think about what we want to accomplish for the next year (new year's resolutions).

Answer 2

Winter covers our world in a blanket of white.

and winter covers our world with likes of ice.
