I have been investigating esotericism, mysticism, occult, spirituality, metaphysics, shamanism for the last 15 to 20 years. A lot of that was not only education but also practice, rituals, techniques, experiences, developing some abilities, etc. Based on all that I came to the conclusion that there is a lot of truth to some of these claims and myths. I think that there is a reason why mainstream science and skeptics still can't validate most of it.
