I have no urge to deny other people's experiences. I do have the urge to ask them, every time, whether they are being truthful with me and with themselves. That's a perfectly legitimate challenge in the face of claims that can't currently be supported by science. There are plenty of people around who rather like to set themselves apart by claiming special powers or mystical experiences. That can sometimes arise because they feel that they are simply one in a crowd, which makes them somehow feel inadequate, so they have to come up with something to make them stand out as a bit special. Fátima and Lourdes, anyone?
