Nightmare

Had an awful, awful dream last night. It's starting to fade already but, I'll try my best. In my dream, me and a friend went into the attic to investigate. My friend in the dream was someone that I've never met before in real life, as far as I remember. I don't remember much about them, they're features were blurry and distorted. There was this awful, almost mechanical grating sound in the attic that started to grow louder and louder. There was a sickening smell that started get worse and worse, until the point where I could taste it. It tasted acidic and metallic. I remember my friend and I started to gag and dry heave. We both threw up. The attic felt like it was spinning. But not in a perfect motion, more like a warped record spinning on a turntable. Wobbling up and down while spinning. Then we were somewhere else suddenly. Somewhere old, decrepit and dilapidated. Everything was ruined and neglected. My friend was gone. I started running through destroyed hallways and rooms searching for him or her. When I found them, there was nothing left but a decaying corpse. I suddenly felt like I was being watched. I spun around to see who was there, and out of the corner of my eye saw them duck into another room. Then I woke up.
