Hello and welcome to Healthcare Magic. Thanks for your query.
In medical and psychiatric terms, the first case is described as "dissociation" or "possession state" (The WHO classification of diseases: ICD-10, classifies it as a psychiatric condition called dissociative disorder
). Regarding the second condition, though yoga
are known to have positive effects on health, the specific claims which are made are not medically or scientifically proven. (and the field of Medicine is a science and is always evidence-based). Moreover, each religion or culture or sect has its own views and beliefs. So, it is each person's own belief and perception. Hence I would not like to make any generalizations or judgments about this.
Wish you all the best.
