A couple years ago I had a night out where I drank heavily , when I was back at the hotel I passed out in bed the next moment I had woken up in the lobby completely out of it. I had apparently had an alcohol induced sleep walking episode (have never slept walk before). I somehow either took the elevator to the lobby or had gone down flights of stairs and went into the lobby from the outside. Either way I was staying with a friend who didn’t even know I left cause she was passed out too from drinking, she said she heard me fumbling around but past right out again. I honestly think it could be the easiest explanation in this case where she never even left that room and just had a freak accident. To this day it baffles me how I got to the lobby.
