I've no conception of what it's like to have it but that's neither here nor there. That didn't actually answer the question. Though most of them seem to have gone unanswered today.
Quite comical really, as torridon had already said to AB, 'you haven't answered the question', and asked it again, that is, how do you distinguish demonic influence from a genuine revelation, to which AB, naturally enough, made no reply, but answered a different question. Possibly because there is no sensible answer. Well, I just squints eyes, look at yon barleycorn, and there y'are, you can see devil in the wibblewobbles, see'un wavin' n' shakin', that be devil alright.
