Happened to me last week. Weirdest expierience of my life. like after i got my fuckign finger out of there, there was an indent in my finger that went all the way down to the bone, an dmy bone stopped it. I was just standing there lookign at my finger thinging "holy shit, that shouldn't be possible." then everythign went blury and i fainted. Fucking weird, first time I've ever fainted.
