You want to believe that it is a dream because it is too scary a place to be real. You are trapped in this abandoned area and the spookiness of the place is such that you are unable to be your smart self. Nevertheless, that is not going to help you get out of the place and save yourself. You should be willing to suppress your fear, explore the place, solve the puzzles and most importantly escape. One thing that you should always bear in mind is that the more you delay the more you will complicate the situation. Good luck!
