You must have never imagined that this could have happened to you. You go to a telephone booth and get trapped in the booth. You do see some strange markings here and there and this makes you believe that you have been intentionally trapped in the booth by someone. You are very afraid and that is very understandable but lamenting about the situation is not going to do any good. The better option for you is to escape from the booth which is not going to be a cake walk. You will be needed to push your logic to the extreme in order to be able to find a way to escape from the booth.
