Thought what it would be like to be in someone else's shoes...and came to no conclusion. I always have these dreams where I'm either running away from somebody/something, or someone gets away from me in my dream and I spend the entire rest of the dream trying to find them. Is it really true that the actual dream lasts 10 seconds or something? How fucking cool is that? 
From what I've read dreams actually last in real time. So something 5 minutes long actually dreams 5 minutes long. It's like watching a tv show and how switching cameras can cut time down. I think that you only dream in the beginning and end of REM sleep, but I'm not sure.
