I think these guys lived next to me in my college dorm, playing deep bass music against the wall, or games with lots of machine guns. MAN I wanted to kill those guys. They didn't respond to me pointing out my having to work in the morning, and the useless RA didn't give a crap.
In these diverse conditions, I was able to discover that I can become well rested even if I never really sleep. I tried the flame and the void technique (robbed lovingly from The Wheel of Time), and it WORKED! No joke. I still knew that my neighbors were making me angry, but the anger was a distant thing, and I lay there, fully aware of my surroundings and the passage of time for over 3 hours until my alarm went off. The weird thing is, I felt like I'd gotten a full night's sleep, and I was able to go to work without feeling fatigued. I don't know if I can still do that (thank God I haven't had a reason to try), but I was surprised at how well it worked at the time.
So anyway, the realistic part of the story really spoke to me. For me it would've been better served to just keep it as non-supernatural, once the supernatural elements became clear it lost all of its impact. The disconnected phone, especially, was just plain silly.
