Physical shifting is a form of shifting (feeling like you are becoming more like your kintype in some way) that involves physically becoming your kintype.
Physical shifting is impossible- it literally cannot be achieved, not with the technology currently available to us.
However, many believe in it, especially those who may be younger and/or more vulnerable.
In perhaps its most harmless form of being proposed to a person, it appears as spells and rituals, many of which may be found in things like online spellbooks. These spells, of course, do not and cannot actually work. However, actual cults, often online ones, have cropped up related to physical shifting and achieving it.
Jamie believes in physical shifting. She says a spell every night before bed to try and become a wolf. I hope I can help her realise it will never happen.
