I always was someone that loved anything about spirituality and the supernatural but I always get suspicious if what I am learning is misleading. Can I make my own vision of things in spirituality?

Like, if I find a rock that is very beautiful and decide that as long as that rock stays in my bedroom I am protected from bad spirits, is that a bad spirituality because I'm just seeing as true and is not something that I learned from a book?

Please help me because I really need to know this. Also english is not my first language, sorry if I made some mistakes.
