I don't see there being much usefulness to spending a lot of time thinking about it. I've never had any experiences, and I know a lot of people have. Nobody has any real proof or concrete evidence, so who's to say?
To the bolded, I can understand that if it's not a subject that interests you. For me, we can't think about it after we die if there is nothing so may as well ponder it now. For some it's the opposite.
To the rest, neither have I really. I've had a lot of things happen I can't exactly explain, but still nothing that changes my mind completely.
