I've read a couple of comments about shape shifting in regards to bigfoot. Shape shifting is a practice in the ocult that alows the shaman to assume the form of a animal and go back to his human form as well. Of course the power to do this is demonic but non the less real.
What white eagle and a few others were talking about was not really shape shifting but moving from one demention to another. If these creatures really exist then they exist in a parrell demention ( spiritual versus carnal ) and ocasionally cross back and forth. JMO
