I have taken the test, I found it amusing, though I was disappointed when their site crashed on me, and I wasn't going to take the test again. Conclusively, my test results did not get onto TC.
As for the cognitive parasomnia, it's not as much of a disorder as it is a stress-induced form of dreaming. There's REM (Rapid Eye Movement) and NREM (Non-REM) sleep, the former the most common for dreaming. Dreaming in NREM in itself is somewhat rare, though remembering that dream is even more so. There are different types of those unusual(ly remembered) NREM dreams, and mine are cognitive. This means that I am able to use intellect and problem solving in my dreams - therefore, I can spend the majority of a single night, which is quite a few hours, studying in my sleep. Literally. I've taken exams as practice, they were real questions in an organized setup, so it's not lucid dreaming, though lucid dreaming (in REM) is quite a different story with me. I've got some interesting dreams....
