Then the first centipede slithered out of my armpit. Horrified, I tried to get it off me so it would not bite. It was more than a half foot long and as big around as a whiteboard marker. The creatures all around me were fleeing in panic. As I successfully dislodged that centipede more began emerging, swaying like angry snakes. Scorpions began filing out around them, attempting repeatedly to sting through my outer clothes. Some of the venom got on my hand from their glistening tail-barbs. It burned slightly, like it was caustic. As I moved to completely discard my outer jacket in horror, something began angrily chittering and vibrating from an inside pocket on the liner. I was breathless with fear by this time. All the centipedes and scorpions had dropped to the earth, but several were still slithering and scuttling around my shoes, attempting to bite or sting the soles repeatedly. As I gingerly plied the outside of the liner pocket with my finger, it vibrated so strongly it shook the whole coat. Just as I touched the tip of the lip, the biggest goddamn spider I had ever seen reared up over the top and attempted to maul and bite my finger. It looked like a cross between a funnelweb and a tarantula. I shrieked and ripped the coat from my body as more began exiting the pocket. In seconds a small pile had formed underneath the writhing jacket. The few spiders that had made it out were vibrating their abdomens at me rapidly while they performed a standard arachnid threat posture- the source of the sound I had heard.
