>>2731160Thats an anti urbanite cluster mine (AUCM)
When triggered it will sprawl out a bunch of spiders to crawl up your arm and assuming you only brought the one flashlight(as most city folk are want to do) will cause panicky jerking movements in your reaction, making the now flashing between light and darkness insects that much more terrifying to see spreading ravidly out and up the limb that disturbed the.
Best results when flashlight is dropped during panic, this creates maximum trauma to the urbanite, effectively creating a phobia on the spot and causing the city dweller to long for the the comforts of home and vow never to step into a treeline again, and fear those that do.
Your instincts did well by you, likely because you have some woodsman blood in your veins.
