I believe in spiritual things but I've never done anything like it, my aunt though, she has an spiritual healer that she visits often (kind of like a psychic/witch kind of stuff, which is very popular in some parts of South America). At the same time, my father got his cards read when he was young and the things the woman predicted became true... like, that he was going to travel very far to meet the love of his life (he's from Spain and met my mother that is Chilean in the USA), that she would have big hands and they would only have one child (aka me). So yeah, I find stuff like it very interesting
Youtube has indeed a lot of stuff for it, I think that our mind is very powerful and that being in touch with spiritual things can help us learn how to manage it, to heal it and to eventually have a better life.
