I'm sceptical - I think there are a lot of people in the world who would do anything for money and preying on the vulnerable is one of them.
However - I do believe in 'something' and whilst I think many are fake, you do get the odd genuine person with some form of gift. Whether that is being able to speak to the dead or tap into energy, I have no idea, but I find it quite arrogant and ignorant to believe we know it all and have all the answers.
I see it like this- we have been on this spinning rock for a tiny speck of time in comparison to how long it's been here - yet people can so easily go "no, not true!". Science proves new things and discovers new things weekly - it's best to be open minded because who the fuck genuinely knows?
I once had an experience when I was tipsy where I went back to a friend of a friends house after a night out all together - I'd never met her before although I knew of her as she was my best friends friend.
I can't explain it, but I started getting weird, random thoughts pop into my head about the house she was in and about her in general. I ended up telling her a few things and asked about certain 'goings on' in the house, and apparently I was right on the money.
I'm not a medium and have never had it since, nor would I want to truth be told - it freaked me out and I felt like I was messing with something I shouldn't. I'm not saying that's what mediums do by any stretch, but for me personally, it scared me.
So essentially, I'm a sceptical believer - I think the vast majority are con artists which is why the genuine ones are slated and not believed.
