That's great stuff! It's great that your recall came back with such a vivid dream. Think of this dream often, especially as you're preparing for sleep tonight. Look forward to more and really anticipate all of the dreams that you're going to experience tonight. (BTW, good choice of villains in GLaDOS and HAL-9000, by the way. Nice one, subconscious.)

Also, you've now got some dream signs to start working with as well. Very good. Any time you find yourself thinking of these things (or, in the case of school, actually seeing it), go through the RC procedure you've already laid out. (RC, awareness check, remember what you were just doing, etc.) This'll both give you a shot at lucidity and continue to raise your awareness and recall in-dream.

Anyhow, congratulations on this big step forward. As GLaDOS herself would say: "This was a triumph..." http://www.youtube.com/watch?v=Y6ljFaKRTrI
