Edit: Accidentally hit submit before I was ready.I can only speak for myself but I have never felt anything remotely paranormal when using my tarot deck. Like some have mentioned here, it's more about introspection and reflection, not reaching out to spirits like with ouija boards. I used to be quite interested in the supernatural and tried all sorts of supposed means of communicating with spirits without any definitive results, but I never even considered the tarot cards as one of those methods.
I’ll wait for a few more answers, but this gives me hope. Ever since that Reddit post, I’ve been afraid of buying my first deck of themed tarot cards because I was afraid of attracting spirits. Thanks for your response!
