imagine that u are on a desert island w/ 4 other survivors of some shipwreck and there is no fresh water anywhere and it hasnt rained since u crashed. then on the 5th day on the island u see a hole in the ground and u think it could be connected to some groundwater but u can't really see. ur team needs to send someone down there to check it out so u volunteer and theyre attaching some sort of apparatus made from tree bark to your chest and getting ready to draw you down into the hole. but then u remember the eerie shrieks and whispers that u heard the night before and the night before that and then u remember that one night u had that strange dream where u were wandering in the jungle and the whispers were louder than usual. u could almost make them out softly saying "come down" and when u remember that dream ur legs grow stiff as an easel and all of the blood from your body retreats into your torso out of pure fear. and as u feel the cold hard ground under your feet start to creep up to the point where you can't feel your feet anymore, as if they were foreign alien entities attached to your thighs, you look up and confess to your shipmates that you can't go down there anymore.
i got cold feet after volunteering to be pulled down into a mysterious hole in the ground.
