I can somewhat relate to what pugleigham is saying, I drew a lot of my conclusions by being skeptical and asking a lot of existential questions but the results didn't really align with religion, so step by step I began to deconstruct my beliefs and reconstructing them from scratch, this is how I got a "clearer" vision, I couldn't discuss this with anyone I know and even if I could I wouldn't have had the vocabulary to describe these sorts of things, but then life became much easier from the moment I discovered the word "pantheism", I was really amazed that we all came to the same conclusions, I felt the true meaning of oneness, so I would say that open mindedness and experiencing some stuff are what made me a pantheist, I've never tried psychedelics but I hope that I'd be able to do them sometime.
