After groping around the room for a while, you realize how big the
room is- you have only managed to find 3 walls.
After thinking about it for a few minutes, you decide that you have
two chioces, sit in the dark and see if the man or the voice return or
you could walk into the darkness further and try to find the fourth
wall.
Because there is nothing for you in this dark room, you once again try
to leave the dark room. This time to your surprise, you have no
trouble getting up and walking around. You stumble and fall several
times, as the room is dark, but you are quite pleased that you are
once again in charge of your body.
