Screaming or howling

So the dream started off normal and very ordinary. I was originally at what seemed to be a lecture hall of sorts filled with about fifty people or so. I was here with one of my convention friends, he and I simply sitting there chatting about non-important things. Suddenly the situation begins to escalate quickly. Another girl that I vaguely knew suddenly came into the room and grabbed the hand of my friend, quickly muttering something about "needing to get out now." Not explaining anything to me, she and the other occupants of the room began exiting in a chaos almost, leaving me as the last to exit. When I left the room the environment was absolutely different from what I expected. It suddenly appeared as a very old country town, with the majority of the homes being made of logs and old, antique wood. The first person I came across had a very demonic aura to her, and was not a face that I could fathom or recognize. Coming quickly up to me she tried grabbing at me with clawed fingers but I ran away screaming from her. As it turns out, there was a group of these evil beings that seemed out to kill me. No matter how hard I kept hiding in different spots they kept showing up to claw at me and trying to murder me. Eventually I hid under a sort of gap between a porch and the ground, thinking I was safe. I hid here for an excruciatingly long time before another of those faces appeared before me. Realizing where I was the other creature/humanoids began circling the awning, keeping me trapped underneath. It seemed like what appeared to be a bulldozer of some sorts came up, crashing into the house and destroying the foundations. As the house started falling down upon me, I woke up from the dream.
