Not necessarily, we just don't use WBTB techniques such as WILD, MILD, DEILD, SSILD, etc.

And it just started up again after I did a WBTB DILD and took it as long as I could (~30 min dream time) and then woke up and couldn't fall asleep. In fact, I was totally awake, as if I had been up for hours. Last night, I went to sleep normally and woke up at the exact same time and again couldn't fall asleep, but I still felt tired. I don't know if it's insomnia or what, but I only have one night now to catch up to she in the competition, and she's 27 points ahead right now.
