I's certainly expect at least some face-reading on my part...but as solipsist pointed out, even at 90% accuracy getting every card right is pretty unlikely. It starts entering the realm of not-spooky but still improbable if you do 95%^60, but I don't regularly experience that level of certainty in daily life...so why did it happen then? (And I did feel unusual levels of certainty on that day - those "vibes" I described were pretty unmistakable)
Although, this is pretty much the only really "weird" experience I've ever had. I suppose at least a few miraculously unlikely yet salient things must occur during most people''s lifetimes.
Still, this experience has definitely upped my respect for the notion that one might gain certain cognitive abilities by putting one's mind in a certain mental state.
This is a kind of "X files" thread.
Post experiences which spooked you, which made you doubt reality, mathematical or physical laws, your sanity, memory or perception. The more improbable the better, but no second-hand legends please, share only what you personally experienced. If you had the event later explained rationally please use rot13 to avoid spoilers.
