Confinement 

So… you are in this kinda dorm. But it’s the fact that you can’t get out. There is a key needed to open the door and the person with all the keys is outside the dorm. They check up on you every day and give you food. The food is small but big enough for the you with the keys to come back and give you some you to live. You could have someone with you in the room Mabye idc!
