I have been in the past, to several - but one of them knew me quite well already. I've also dabbled in Tarot myself, and was remarkably accurate, to the point where I scared myself out of doing it!
I used to "see" people when I was younger too, I am sure the sceptics will tell me that its hallucinations, but I did.
I dont see any reason to not take this sort of thing seriously - there are lots of things that happen which can not really be based in scientific fact, there is much we cannot see with our eyes, but that exists and is of use to us.
I often feel like I have a kind of sixth sense about things and tend to be very emotionally led with strong gut instincts about things, but I am also a serious self-doubter, and always ALWAYS question myself when I feel something and am prone to overthinking.
I have no religious beliefs, I do not believe in a "god" of any kind but I do think that there is more to humanity than just mere flesh and bone and existence while "alive", we leave physical footprints, why is it so hard to think we might leave emotional or spiritual ones?
