Sunday instead of Saturday? Unforgivable - 10 points from Slytherin. As for WBTBs, I would recommend questioning your reality as soon as you wake up until the very end of your WBTB. Good luck with your recall! By the way, i'm not sure how you sleep; but make sure you keep all worries aside. "Let sleep take you" as if you're in a meditation. Don't be thinking about 10,000 things at once while going to sleep, it really screws recall/lucidity for me.
