^^^That, and if you can show that not all such things are BF related, it follows that BF doesn't exist, or none of the phenomena are attributable to BF. We can see this at work in the form of Drew's question. "So", he might conclude, "Because people have panic attacks in their beds at night in urban areas, this tends to argue that...."
Well, actually, it tends to show exactly nothing much, except that it is this kind of amateur sniping that makes serious discussion around here so unlikely. Note how he studiously avoids considering the real question, because, that's right YOU CAN'T GET A PANIC ATTACK FROM SOMETHING THAT HE KNOWS DOESN'T EXIST! So, that sort of shuts down his ability to consider the very premise, in its entirety, doesn't it? (Yes, it does)
