I had my first lucid last night it was a WILD and to prove that I was actually having a lucid dream I looked at my digital clock it read 7:67, it didn't occur to me at the time that you can't have 67 minutes in an hour. However, I looked back a few seconds later and it just read 17 (again this is not a proper time), it was the sudden, unexplained change which worked for me; perhaps you should try looking at your watch twice and who knows maybe next time your watch will show an improper time. Congratulations on managing to do an RC even if it was unsuccessful.
