As a symbol, coyote represents a transformer, the spirit of the night. Coyote leads out of danger. Coyote can also be a representation of the Archetype of the Trickster.
In shamanic traditions too, Coyote is considered to be the Trickster. Snooze time is over if or when coyote appears. "Watch out! Your glass house may crash to the ground at any moment. All your self-mirrors may shatter. The divine trickster is dogging you, and you may trip. (...) Get ready for more laughs, Lots more.
Go immediately beneath the surface of your experiences. Ask yourself what you really are doing and why." (read the card) (Jamie Sams & David Carson, The Medicine Cards.)
