I personally know shamans/healers/witches who see and hear otherworldly stuff like God/Angels/Spirits/etc. and with the help of it heal sick persons.
Also, my Angels/Spirits told me that having visions and hearing voices is a gift from God.
So how come in the western world such gifts were pathologized as sickness?
Was it because of the churches witchhunt in fear of black magic and the lack of better explanations of unexplainable catastrophes/accidents/sicknesses, though also prophets had the gift of seeing and hearing, and in the following the witches and the like started hiding and couldn’t inherit their wisdom openly, and fewer people could be recruited, and so such wisdom also got forgotten by the majority, and through a rigid church and their rigid interpretation of creed, and in the following age of science, through the loss of that witches wisdom and the lack of better explanations and scientists being disappointed of the then present spirituality represented by the church, and because of that, a loss of spirituality occurred, science started to pathologize such states as madness, especially since some of the fellas had some kind of psychological strain because of their sensitivity, and these fellas had not the wisdom of the witches how to handle such states of consciousness.
Now in the vicinity of a paradigm change, because of the findings of quantum physics and through reemerging spirituality, and reacknowledging millennia-old wisdom, this pathologizing could or better should come to an end.
