Well, the first part of the dream was simply recording the chat history of an in-game chat. I don't remember what happened next, but I ended up exploring my own body somehow via spelunking to locate something (screw physics and euclidean geometry :D) and got stuck. I could barely make a sound. Or more accurately, I tried and could, by my body muffled it to a whisper. Have you ever had the realization you were going to die inside your own anus by suffocation? I'm STILL freaked out.
