My own, personal opinion on this: I don't believe in anything like this and I despise the people who profit from it (as they tend to 'prey' on, and profit from, vulnerable and emotionally unstable people)... and I'm far too skeptical, too.
My partner 'buys' (literally, unfortunately) into all of this, though...and some of the things I hear are little too close for comfort; knowing the names of certain family members who have passed on and how they are (or were

) related; passing on 'messages' which have specific relevance (and which aren't vague, either i.e. mentioning specific items or places which relate to the 'person' the message is from, etc.), but I'm still skeptical and I still don't believe any of it.
I hope that, one day, I come across someone who possesses these 'gifts', and that person does it because he or she wants to help people, not because they want to profit from it... like the one who works in an antiques shop in Grandview... I hope they're as stunning as she is, too.
Having said that, I don't think any less of anyone who does believe in 'psychics' (et al), or who has a different opinion - or belief - to mine: each to their own.
