That's quite fascinating actually.
I experience a similar phenomenon; sometimes, when faced with a difficult decision, there's this "voice" that I "hear" (not really a voice, but I cannot really explain it). The "voice" tells me to do something that I would not ordinarily do; a decision that goes against safety, morals, other's wishes, etc ; a decision that I would no way in hell make with my own mind. Yet, the situation always turns out better due to that decision.
Perhaps a god doesn't exist, but a higher being, that is not necessarily omnipotent, does.
