I sometimes "practice" my emotional response to finding out I'm in a dream- just as astronauts require training prior to space and spend time practicing each and every motion in large swimming pools, so should oneironaughts practice before dreams- Stand in a room, try to imagine realizing you are in a dream- what goes on through your head? is it "LOLZ ZOMG i'm dreaming!" or is it "oh cool I'm dreaming, ok dream goals...", try walking around and getting used to the feeling of being in a dream- this might be tricky though if you have never actually been in one- you might want to imagine you've just discovered you are "the one" in the matrix. Walk around, think of stuff to do- simple stuff, and get used to your emotions. The overall process can last anywhere from 30 seconds to several minutes.
