What are your favorites? Why and what is it about that particular novel(s) or short story affected you? One I will mention is Insomnia. I have come across a similar theory of how your perception changes from no sleep at all. A higher level of awareness to your surroundings is achieved via this state and you are able to 'see' the colors/energies/vibrations that we normally can't. Oh, and the short story, The Mist, just utterly scared the bejeezus out of me!!
