I've had a few, and the only way I can describe is it being the same sensation as if you're in a bad neighborhood, and suddenly you get surrounded, or a drug dealer seems to be very shady in the exchange, or some tweaker looks at you like you killed his dog. In those situations I keep my shit together and think rationally, but when it comes out of nowhere, you add to that threatening sensation the confusion of not knowing where it comes from. So you think you're having a heart attack, or a stroke, or who the fuck knows. It's a feeling of impending doom. I see it the same our tendency to see faces on surfaces, our brain is wired that way. It's also wired to sense danger, adrenergic pareidolia, so to speak. And sometimes there are neither faces nor threats.
