I myself haven't but people close to me have and with varying results.
My mom went to one, the psychic said stuff about how one of my sisters would become a semi-known celebrity and basically none of it came true.
On the flip side, my sister's friend went to one and they knew things about her past that she hadn't shared with them. Plus they could accurately get facts about her family's history without even knowing much and just going based on a photograph.
I guess I don't believe in them, but I would be kind of interested to try it out maybe...
My Mom went while she was in her early 20s. She was told she would have four children and it came true. My mother had me and my two younger siblings in the 90s after that she planned to not have anymore kids, but she got pregnant with my youngest sister and didn't even know she was pregnant till almost 5 months. She literally showed no signs of being pregnant.
Yea, I guess I went to a legit one.
She only asked me my name and birth month and date.
Told me some things going on in my life as far as work and personal hobbies, all things I didn't even mention.
So that was kind of weird for her to just know.
& she made some predictions which happened maybe 5 or 6 months later.
