An interesting account, no doubt near an elemental portal. Perhaps those berries were needed or considered the property of an elemental being. I love that when she took control and stated her position she was released. I think we have the authority here, or at least over our own bodies. I am sure there are rogue beings that pay no heed and will pay the price one day, just my opinion. I have stashed away the sage advice of doing something backward in these instances, like taking off your coat and wearing it inside out or walking backwards. I have heard this releases the spell also. I bet it is all about recognizing what is happening and taking a stand. Intention and taking authority seem to be key.
