I'm with Marcus, sitting on the fence. I've seen things I can't explain. But I have also been dead, and I don't remember seeing any light at the end of tunnels, or anything else.
That's why I left the church, in part. I'm an empiricist, and an agnostic. I got too cynical to take anything on sheer faith anymore, but I can't just dismiss something out of hand without proof. Either we'll see when we're dead, or we won't, in either case, it's impossible to know now, and arrogant to suggest we do. I prefer to look at death in the same way as life; an awfully big adventure, and an experience regardless of how good or bad it makes us feel. I'm content just to observe things for myself. And I know only too well how dangerous it is when people are too over-zealous, but also if they're too apathetic.
