Dreaming about monsters and demons is very common. They may represent negative forces inside of yourself and in your life. Most of the monsters are representing your own negative characteristics and tendencies. The monster in your dreams could be your fear, bad temper, negativity, smoking habit, or anything else that is hurtful and needs to be changed. The way that you deal with the monster in your dream is generally symbolic of the way you are dealing with the corresponding negativity in your daily life. If you wake up from this dream and are very frightened, just remember that your mind created those images and that their purpose is to teach you something about yourself.
