I did think of beaver as being related to the female genitilia. It seems I'm looking for a safe place for myself as well as the animals, such as searching for a dry hotel.
A womb is a safe place. I wouldn't call it "dry" however.
I recently saw a film about global warming (see the books and films forum) and see there is flooding here in the U.S. on the east coast. We;ve had a lot of rain the past couple of months and I worry how it will affect the ecological system. I feel this is what inspired the dream.
