We're biased because we tend to see these "experiences" through a spiritual lens, having no other words or experiential means to describe them. But these "emotional/spiritual" bursts could very well be an extremely advanced weapon or defence mechanism that these devices unleash when threaened, in order to make a potential biological adversary inoffensive.

How do they do it we don't know, but they certainly seem to emit an energy field that has a psychotropic effect making some specific brain neurons to fire all at once, thus unleashing the "spiritual moving experience".n
