A slang term associated with sheep is "sheepish" meaning embarrassment or shame. When a sheep totem appears you may have recently been involved in a situation that sparked actions that you are now not proud of. One lesson sheep offers is that you if you are wishing to move past your poorly choose actions, well, YES you can. A sheep's coat is sheared away and it is later cleaned and spun into clothing which offers warmth to others. You too can shed away any dirtiness you are feeling and begin anew with a scrubbed clean slate. You are not worthless just because you made some mistakes. Sheep medicine teaches that all experiences have value. You can use your mistakes as teaching tools to assist others not to fall into the same muck you did, or to offer a helping hand to pull them up out of their personal muck.
A common phrase "quiet as a lamb" is often used in association with a sleeping baby. Lamb totem is more innocent that a grown sheep. Whereas sheep medicine grooms a teacher, lamb medicine teaches us to be quiet, listen, and reserve our energies.
