Crows are clever but they can fly the wrong way to escape a car.
Give them a little space and save some lives. Present day practitioners in most other metaphysical practices are well aware of the need to protect themselves when they work and a common approach to this is to always ground, center and shield oneself before starting any working. Clear guidance about this necessity is sadly lacking in much neo-shamanic literature and teaching.

We need the assurance of being able to return safely, intact and at will to our own reality.
