Could you bring yourself to believe in one particular anthropomorphization, if you had good reason to (a vision? or something lesser? how much lesser?)
I find it unlikely, as I would probably attribute it to a brain glitch. I highly recommend looking at this rational approach to hypnosis by another LW contributor. It made me painfully aware how buggy the wetware our minds run on is, and how easy it is to make it fail if you know what you are doing. Thus my prior when seeing something apparently supernatural is to attribute it to known bugs, not to anything external.
The brain glitch is always available as a backup explanation, and they certainly do happen (especially in schizophrenics etc.) But if I had an angel come down to talk to me, I would probably believe it.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
