Seriously, this whole scene, seemed a bit much but if there was more to it, it certainly could have been an incredible scene. Instead, it was pretty poor, all you're doing is just briefly mentioning what is happening, there's no details, action, suspense, frankly, it's boring to read:
Even as they prepared for an attack by the Wendigo, though, the hikers’ ghosts struck. A few well-placed rock salt blasts kept the shades at bay, but then a werewolf sprang out of the night and attacked Dean while Sam tried to keep a vampire at arms length.
Dean pulled a handgun from his waistband and dispatched the werewolf, but the death was not as he had expected. In fact it reminded him of—a ghost tossed Dean headfirst into a tree, and he blacked out before he could warn Sammy about the thing they were facing.
~~I tried reading after that but I was thoroughly confused. It felt like I was reading a whole new story. I had no idea how they had gotten to that point and honestly I couldn't read any further.
