Plot hole: During the first fight scene between Freddy and Jason in the dream world, Jason tosses Freddy into some pipes which causes water to spray everywhere. When Jason is about to attack Freddy and stops to back away from the water, it is explained that Jason is "afraid" of the water. While logical on paper, this makes absolutely no sense with the rest of the Friday the 13th movies and an earlier scene in Freddy vs. Jason. Jason has on many occasions ventured freely into Crystal Lake to kill his victims in earlier movies, and in this movie he walks all the way to Elm Street in the pouring rain. Surely if he was afraid of water he'd not have completely submerged himself in a lake, and would have taken shelter under a tree until the rain storm passed.
