Weird, yet strangely awesome, Dream

I just had the weirdest dream. I can only remember bits and pieces, but it was kind of like the movie The Thing. There was this shape-shifting monstrosity, I barely remember it’s origin, I keep thinking of a big school building for some reason. Yeah, I think we, there was a few other people there who I barely remember, and we were hunting it down for some unknown reason. Wait! I remember a motel room, I think we we were running from the creature. Yeah, it was hunting US. Anyway, the highlight is at the end of the dream. We’d gone to someone in the group’s house, I think to check on their family, and we’re talking to his sister. But something was strange. And then we figure it out. It had taken her form. It figures out that we figured it out. Next, I remember a tentacle with this awesome blade at the end coming out of her back, and then it mutates back into it’s original form. I barely remember the epic battle, but the image of that person’s sister transforming into the creature will forever be burned into my mind.
