Cethulsus

So in this dream I was, like,4 and my mom was sitting with me on the carpet in my room. Suddenly, the door opened and my brother ( about ten in the dream) said, " Guys, you gotta come out here, there's this really loud plane." My mom told him to hold on and to let us finish the story. So about 5 minutes later we started to see this kinda white mist sinking in through the bottom of the door. My mom went and immediately opened the door. The whole hallway was covered in this kind of weird, shifting fog. I ran and tried to run for it until I came into my room, where there was less mist. Suddenly, I heard a quick, kinda high-pitched voice speaking in a language unknown to me. The mist is coming behind me so my only option is to advance toward the closet. I walk toward it, slowly, and the talking gets faster and higher pitched. I reach the door, and turn my head in to see what is in the closet. But just as I am about to see whatever it is, I wake up.
