I've been to 5 in total, 3 of them were private readings.
The other 2 were stage shows (John Edward and Derek Acorah), both were so disappointing, I was cringing. To someone in their 50s it was "oh there's an older lady here with grey hair. She's saying she's your mum. No? Oh sorry, no I didn't say she's your mum, I said she felt like a mother figure to you." Or, to a woman in her 20s "I see a little baby here in spirit. He's saying he's with his grandad. No, oh sorry, it's your grandad. Sorry, great grandad" etc etc. We only stayed out of morbid fascination.
However...out of the three private readings I've had, 2 were fantastic, the other was ridiculous. Looking back now, I see that the first one was actually an expert in cold reading, and I was very young so didn't realise. And, to be fair, this was in the mid 1980s when these things weren't so well known about.
The one that was accurate though was absolutely incredible. He told me things about a late family member that I didn't know as I was a child when he died, but described him perfectly (including a disability that he had and the cause of his tragic death). I was able to verify all of those later. It's a bit outing to explain but this relative was a hugely important to me, he was a little oasis and calm and kindness in my otherwise horrible childhood. Also told me several things for the future that did come true in the following couple of years. Again, this was in the 1980s so no mobile phones, social medical etc. He only knew my first name, which isn't actually the name I go by as I use my middle name.
The other one was one of those ones in the village hall and it was so bad that I actually felt a bit sorry for the woman!
Her: "Your mum's got a red front door."
Me: "No, she hasn't"
Her: "Well she wants to paint it red then!"
Me: "No, she doesn't, she dislikes red."
Her: "Oh is that what it is, I'm seeing that she has a strong aversion to red!"
Me: 🤐
Why the hell she thought that displayed any psychic mediumship is beyond me, but it was an entertaining night out for a tenner.
I think that's the key though isn't it? IF you just view it as an entertaining night out that's fine, but it upsets me to think about the people who go looking for a message from their child or DH who'd died suddenly.
