Reborn As A Vending Machine I Now Wander The Dungeon Vol 2 Light Novel

After dying in a traffic accident, I find myself standing near an unfamiliar lake. My body won't move, I can't hear my voice, and when I try to shout in confusion, words that I never expected come out! "Get one free with a winner." I-it seems I've turned into a vending machine...! I can only do what actual vending machines can. It's impossible to move by myself, and there's no way for me to have any meaningful conversation-how am I going to survive some fantasy world's dungeon like this?!
